Perinatal Mental Health

NICE CG192Postnatal depressionPsychosis = emergency

Blues ≠ depression"Baby blues" — tearfulness, lability, anxiety — affect up to 80% of women, peak around days 3–5 and resolve by ~2 weeks. Postnatal depression persists beyond 2 weeks, is more pervasive, and impairs function and bonding

PND ≈ 1 in 10Postnatal depression affects around 10–15% of women; it is common, treatable, and frequently missed because women hide it through guilt and fear of judgement. Antenatal depression and anxiety are equally important and under-recognised

Ask: self & babyRisk assessment is mandatory: thoughts of self-harm or suicide, and thoughts of harming or not being able to care for the baby. Suicide is a leading cause of maternal death. Ask directly, sensitively and always

Psychosis = emergencyPostpartum (puerperal) psychosis — rapid onset (often days 1–2 weeks), mania/confusion, delusions (often about the baby), hallucinations — is a psychiatric EMERGENCY with high suicide/infanticide risk. Same-day specialist assessment; usually admission to a Mother & Baby Unit

Sertraline-friendlyWhere an antidepressant is needed in a breastfeeding mother, sertraline is commonly used (low milk transfer). Don't withhold effective treatment because of breastfeeding — weigh risks/benefits and involve perinatal specialists for complex cases

Whooley + EPDSScreen with the Whooley questions (low mood; loss of interest) and an anxiety enquiry; the Edinburgh Postnatal Depression Scale (EPDS) helps quantify severity and track response — note item 10 screens self-harm thoughts

Past illness = high riskA personal or family history of bipolar disorder, postpartum psychosis or severe mental illness markedly raises the risk of severe perinatal relapse — flag in pregnancy, make a plan, and involve perinatal psychiatry early

Think widerConsider anxiety/OCD (intrusive thoughts of harm — distressing but ego-dystonic), PTSD after traumatic birth, thyroid dysfunction and anaemia as contributors, and always the safeguarding of the infant and other children

📋 Clinical Stem — Perinatal Mental Health

A first-time mother at 7 weeks postnatal, brought by her partner, tearful and exhausted, convinced she is "a terrible mother" — with intrusive thoughts she is frightened to disclose

Priya Sharma, 31, attends with her 7-week-old baby and her partner, ostensibly about the baby's feeding. She is tearful, exhausted and flat. With gentle questioning she describes 4 weeks of persistent low mood, poor sleep even when the baby sleeps, loss of enjoyment, poor appetite, and overwhelming guilt that she is "a terrible mother" and the baby "would be better off without me around." She is breastfeeding and very anxious about taking any medication. When asked carefully and given space, she discloses distressing intrusive thoughts of the baby coming to harm, which horrify her and which she has told no one. She denies any wish to act on them. There is no confusion, grandiosity or loss of touch with reality. She has no past psychiatric history but her mother had "a breakdown" after childbirth.

This stem tests the ability to: distinguish baby blues from postnatal depression and from the emergency of postpartum psychosis; conduct a thorough, sensitive risk assessment (thoughts of self-harm/suicide and thoughts about the baby), and correctly interpret ego-dystonic intrusive thoughts of harm (a feature of postnatal depression/anxiety/OCD — distressing but not psychosis) versus psychotic command/delusional phenomena; explore the guilt and the fear of disclosure; manage treatment in a breastfeeding mother (talking therapy, and sertraline where an antidepressant is needed) without withholding effective care; recognise the family history of probable postpartum psychosis as a risk marker; and arrange appropriate support (health visitor, perinatal mental health team) with a clear safety-net. The SCA challenge is creating enough safety for honest disclosure and responding to the intrusive thoughts without alarm or over-reaction.

Scenario A — Postnatal depression (this stem) Persistent low mood >2 weeks, guilt, anhedonia, impaired function/bonding, ego-dystonic intrusive thoughts, no psychosis. Risk assess; talking therapy ± sertraline; health visitor + perinatal team; safety-net; review.

Scenario B — Baby blues Days 3–10, tearful, labile, anxious, resolving, function preserved. Reassurance, support, watchful waiting; review if persisting beyond 2 weeks.

Scenario C — Postpartum psychosis (EMERGENCY) Rapid onset (often first 2 weeks), mania/confusion, delusions (often about the baby), hallucinations, severe insomnia, behavioural change. Same-day psychiatric assessment; usually Mother & Baby Unit admission; high suicide/infanticide risk.

Scenario D — Perinatal anxiety / OCD / PTSD Marked anxiety, intrusive ego-dystonic thoughts with checking/avoidance (OCD), or re-experiencing after traumatic birth (PTSD). Talking therapy first-line; SSRI if needed; perinatal team if severe.

Scenario E — High-risk antenatal flag Personal/family history of bipolar or postpartum psychosis identified in pregnancy. Pre-emptive perinatal psychiatry referral and a written care plan for the perinatal period.

Key variables to adapt for Timing (blues days 3–10; psychosis often first 2 weeks; PND any point in the first year); severity and function; risk to self and baby; nature of intrusive thoughts (ego-dystonic vs delusional/command); past/family history (bipolar, postpartum psychosis); breastfeeding and medication choice; birth trauma (PTSD); social support, domestic abuse, safeguarding; physical contributors (thyroid, anaemia).

Steps:

Step 1

History — Mood & Function · Risk to Self & Baby · Intrusive Thoughts · ICE

▲collapse

The history has three jobs: characterise the mood disturbance and its effect on function and bonding; conduct a full, sensitive risk assessment (thoughts about self AND the baby); and correctly classify what you find — baby blues, postnatal depression/anxiety, or the emergency of postpartum psychosis. The decisive interpretive skill is distinguishing ego-dystonic intrusive thoughts of harm (distressing, unwanted, a feature of PND/anxiety/OCD) from psychotic phenomena (delusions, command hallucinations) — because they sit at opposite ends of the urgency spectrum.

🎓 SCA framing — create safety for honest disclosure

"Becoming a parent is one of the hardest things there is, and lots of mums feel low or have frightening thoughts they're ashamed of — it doesn't make you a bad mother, and you won't be judged here. Can you tell me how you've really been feeling?"

Priya is terrified that disclosing her thoughts will mean her baby is taken away. Normalising, non-judgmental language and explicit reassurance about the purpose of the conversation are what make an honest, life-saving disclosure possible.

1A — Mood, function and risk

Question	Why it matters	Changes what?
🟢 OPEN QUESTION"How have you been feeling in yourself since the baby arrived — not just the baby, but you?"	Giving the mother permission to talk about herself, separate from the baby, opens the consultation. Capture onset and duration (beyond 2 weeks distinguishes PND from blues), pervasiveness, anhedonia, guilt, sleep (poor even when the baby sleeps is significant), appetite, and the impact on function and bonding. Priya's 4 weeks of pervasive low mood with guilt and anhedonia is postnatal depression, not blues.In SCA: asking about her, and noticing she came in "about the baby's feeding," demonstrates the awareness that perinatal depression often presents covertly.	>2 weeks, pervasive, impairing → PND not blues
Timing & course"When did this start — and has it been getting better or worse?"	Blues peak days 3–5 and resolve by ~2 weeks. Symptoms beyond this, worsening or pervasive, indicate depression. A very rapid, dramatic change with confusion/elation in the early weeks suggests psychosis and a different urgency.	Resolving by 2 weeks → blues. Persisting/worsening → PND. Rapid dramatic onset + confusion → ?psychosis
🚩 Risk to self"Sometimes when people feel this low they have thoughts that life isn't worth living, or of harming themselves — have you had any thoughts like that?"	Mandatory and direct. Suicide is a leading cause of maternal death. Asking does not plant the idea. Priya's "the baby would be better off without me" needs careful exploration — passive ideation, active thoughts, plans, intent, protective factors. Quantify and act on the risk.Active suicidal ideation/plan/intent → urgent perinatal/crisis assessment; safety plan.	Active intent/plan → urgent same-day assessment
🚩 Risk to and thoughts about the baby"Many mums have frightening or unwanted thoughts about the baby that they'd never act on but feel awful about — have you had anything like that? And do you ever feel unable to cope with or care for the baby?"	The most delicate and important enquiry. Distinguish: (1) ego-dystonic intrusive thoughts of harm — unwanted, distressing, recognised as wrong, no intent (PND/anxiety/OCD — Priya); from (2) thoughts driven by delusional beliefs or command hallucinations, or loss of touch with reality (psychosis — emergency). Also assess capacity to care for the baby and the baby's safety/welfare.Ego-dystonic, no intent → reassure, treat PND. Delusional/command/loss of reality, or intent → emergency. Welfare concern → safeguarding.	Psychotic phenomena / intent → emergencyWelfare concern → safeguarding + HV
🚩 Psychosis screen"Have you felt unusually high or sped up, gone without sleep but not felt tired, had unusual beliefs, or sensed/heard things others don't?"	Actively exclude postpartum psychosis: elated/labile mood, reduced need for sleep, grandiose or bizarre delusions (often centred on the baby), hallucinations, confusion, rapidly changing presentation. Its presence converts the consultation into an emergency. Priya has none of these.Any psychotic/manic features → psychiatric emergency, same-day assessment, likely MBU.	Psychosis → emergency, MBU
Risk factors, support & contributors"Have you had depression before? Any history of bipolar or of severe illness after childbirth in the family? How's your support at home, and is the relationship okay?"	Past depression, and especially personal/family history of bipolar or postpartum psychosis, sharply raise risk (Priya's mother had a postnatal "breakdown"). Assess social support, domestic abuse, birth trauma (PTSD), and physical contributors (thyroid, anaemia). Lack of support and abuse worsen prognosis and safety.Bipolar/postpartum psychosis history → high risk, perinatal psychiatry. Abuse/poor support → safeguarding, social support.	TFTs, FBC; perinatal referral if high risk

1B — Red flags

🚨

Red Flags — the perinatal emergencies

Red flag	Why dangerous	Action
Postpartum psychosis — rapid onset, mania/confusion, delusions (often about the baby), hallucinations	A psychiatric emergency with very high risk of suicide and infanticide; presentation can fluctuate rapidly and deteriorate within hours.	Same-day psychiatric assessment (perinatal/crisis) — NICE CG192: assessment within 4 hours of referral; usually Mother & Baby Unit admission; do not leave mother and baby unsupervised if concerned
MBRRACE-UK red flags: recent significant change in mental state or new symptoms; new thoughts or acts of violent self-harm; new and persistent expressions of incompetence as a mother or estrangement from the infant	These features recur in confidential enquiries into maternal suicide. Violent methods and rapid deterioration are characteristic, so they are treated as warning signs of severe illness even when the woman denies intent.	Urgent senior psychiatric assessment (perinatal/crisis team), same day
Active suicidal ideation with plan/intent	Suicide is a leading cause of death in the perinatal period; risk can escalate quickly and methods may be violent.	Urgent same-day perinatal/crisis assessment; safety plan; do not leave alone
Thoughts of harming the baby with any intent, or driven by delusional belief	Distinct from ego-dystonic intrusive thoughts; intent or delusional drive is a safeguarding and psychiatric emergency.	Emergency psychiatric assessment; safeguarding; ensure infant safety
Severe depression — not eating/drinking, profound hopelessness, unable to care for self or baby	Severe functional collapse endangers mother and infant.	Same-day mental health assessment (perinatal/crisis); consider admission (MBU)
Personal/family history of bipolar or postpartum psychosis	Very high risk of severe, rapid perinatal relapse — needs proactive planning, not watchful waiting.	Perinatal psychiatry referral; written perinatal care plan; vigilance in early weeks
Safeguarding / domestic abuse	Maternal mental illness, domestic abuse and infant welfare are intertwined; the infant and any other children must be safeguarded.	Safeguarding assessment; health visitor; refer per local pathway

1C — ICE

💭 Ideas

"What do you make of how you've been feeling — what do you think is going on?"

Priya may believe she is simply failing as a mother, or fear she is "going mad." Surfacing her model lets you reframe this as a common, recognised, treatable illness — not a character flaw — which is itself therapeutic and reduces the shame that fuels non-disclosure.

😟 Concerns

"Is there something you've been frightened might happen if you told someone?"

Her central concern is almost certainly that disclosing her thoughts will lead to her baby being taken away. Naming and addressing this fear directly — explaining that the aim is to support her and keep mother and baby together — is what unlocks honesty and engagement.

🎯 Expectations

"What were you hoping for from coming in — and how do you feel about different kinds of help?"

She may expect to be told to "pull herself together," or fear being pushed onto medication while breastfeeding. Naming her expectations lets you offer a menu (talking therapy, health visitor support, safe medication if needed) and make a shared decision that respects her wishes about breastfeeding.

1D — Psychosocial context

Perinatal mental illness is shrouded in guilt and stigma — the cultural expectation that new motherhood is joyful makes women feel they are failing, and the fear that admitting dark thoughts will lead to their baby being removed keeps them silent. That silence is dangerous: it is why perinatal suicide and undiagnosed illness persist. The single most important clinical act is to create a non-judgmental space in which honest disclosure feels safe, to normalise intrusive thoughts and low mood, and to be explicit that the goal is to help her and keep her and her baby well — together.

🤱 "I'm a terrible mother"

The pervasive guilt of PND is a symptom, not a truth. Naming it as part of the illness, and separating her worth from her symptoms, is therapeutic.

"That feeling of being a terrible mother is one of the most common symptoms of this illness — it's the depression talking, not the truth. The fact you're here, worrying about your baby, tells me a lot about the kind of mother you are."

😨 Fear the baby will be taken

This fear silences women. Address it openly: the aim is support, and most women are helped at home with their baby.

"I want to reassure you — telling me how you feel will not lead to your baby being taken away. My job is to help you get well, and the vast majority of mums are supported at home, with their baby, exactly where they should be."

🧠 Normalising intrusive thoughts

Ego-dystonic intrusive thoughts are common and frightening; explaining what they are relieves enormous distress.

"Those horrible thoughts that pop into your head and upset you — lots of parents get them, precisely because you love your baby and your mind is on high alert. Having them does not mean you'll act on them; the distress they cause you is actually reassuring."

🤝 Support & the partner

Involve the partner and health visitor; isolation worsens outcomes. Practical support and sleep matter.

"You don't have to carry this alone. With your agreement I'd like to involve your health visitor and, where helpful, your partner, so you've got proper support around you — and we'll look at practical things like rest too."

1E — Case-finding in every perinatal contact: Whooley and GAD-2 (NICE CG192)

🗝 The four questions to ask at every perinatal contact

Tool	Exact wording and what to do with a positive
Whooley 1 — mood	"During the past month, have you often been bothered by feeling down, depressed or hopeless?"
Whooley 2 — interest	"During the past month, have you often been bothered by having little interest or pleasure in doing things?" A "yes" to either → full assessment (or referral to her GP if asked by another professional); the EPDS or PHQ-9 can be used as part of that assessment.
GAD-2 — anxiety	"Over the last 2 weeks, how often have you been bothered by feeling nervous, anxious or on edge?" and "…by not being able to stop or control worrying?" A score of 3 or more → consider GAD-7 and a fuller assessment; if she scores below 3 but you are still concerned, ask about avoidance and consider GAD-7 as well.
When	NICE CG192 advises considering these at a woman's first contact with primary care, at her booking visit, and during the early postnatal period; many services also repeat them at later contacts when there is clinical concern. Priya's "feeding" appointment at 7 weeks is exactly that opportunity.

⚖ Why case-finding matters in this group

Point	Why
Covert presentation	Women commonly attend "about the baby" — feeding, crying, sleep, rashes. The mother's own mental health has to be asked about explicitly, often with the baby in the room.
Disclosure is low	Shame and fear that children's social care will become involved lead to under-reporting. A normalising preamble before the Whooley questions raises disclosure.
A screen, not a diagnosis	A positive Whooley triggers assessment; it does not establish severity or risk. The EPDS quantifies symptoms (item 10 asks about self-harm and must be asked aloud), but clinical interview and risk assessment decide management.
Partners too	Paternal and partner depression is common after a birth and affects the family system. Asking the partner how they are coping is good practice and informs how much support the mother really has.

1F — Past, family, drug and social history: what changes management

Question	Why it matters	Changes what?
Past psychiatric history"Have you ever had problems with your mood, anxiety, or needed help from mental health services — including before this pregnancy?"	A previous depressive episode raises the risk of perinatal recurrence; a previous severe illness (bipolar disorder, schizophrenia, severe depression, previous postpartum psychosis) places her in the highest-risk group. Ask about previous highs specifically — "a spell where you felt on top of the world, needed little sleep, and others noticed you were different" — because bipolar disorder must be screened for before an antidepressant is started.	Severe/bipolar history → perinatal psychiatryScreen for bipolar before SSRI
Family history"Has anyone in your family been very unwell after having a baby, or had bipolar disorder?"	A first-degree relative with bipolar disorder or postpartum psychosis raises her own risk of postpartum psychosis, even without a personal psychiatric history. Priya's mother's postnatal "breakdown" is therefore not background detail — it is a risk marker that lowers the threshold for specialist involvement and heightens vigilance for early psychotic or manic symptoms.	Discuss with / refer to perinatal team
Current and recent medication"Are you taking any regular medicines — including anything you stopped when you found out you were pregnant?"	Women sometimes stop antidepressants, mood stabilisers or antipsychotics abruptly in early pregnancy out of fear for the baby, which increases relapse risk. Valproate, lithium, carbamazepine and lamotrigine each carry specific issues in pregnancy and breastfeeding and need specialist advice. Also ask about over-the-counter and herbal remedies (for example St John's wort, which interacts with many drugs).	Specialist advice on mood stabilisers
Alcohol and drugs"Some people use alcohol or other things to cope when they're struggling — is that something that's happened for you?"	Substance use increases risk to mother and baby, interacts with treatment, and is a recurring theme in MBRRACE-UK reviews of late maternal deaths from psychiatric causes. It also has safeguarding implications for the infant.	Substance-misuse services; safeguarding
Domestic abuse — asked when she is alone"Because it's so common, I ask everyone: is anyone at home hurting you, frightening you or controlling you?"	Domestic abuse often starts or escalates in pregnancy and after birth, and it is a major driver of perinatal depression and suicide. Ask only when it is safe — never in front of the partner, however supportive he appears. In this consultation that means finding a moment alone with Priya (for example, while weighing the baby or at a follow-up).	Positive → safety plan, MARAC/IDVA, safeguarding
Other children, housing, money and support"Who's at home with you? How are things for money and housing? Who can you call on?"	Other children in the household are part of the safeguarding picture. Financial stress, insecure housing, migration, isolation from extended family and language barriers all increase risk and change what support is realistic. MBRRACE-UK reports repeatedly note that women who died from psychiatric causes often faced multiple disadvantage.	Social prescribing; HV; benefits/housing advice
Birth experience and physical recovery"How was the birth for you? And how is your body recovering?"	A traumatic birth raises the risk of PTSD and depression, and a birth debrief with maternity services may be what she needs. Pain (perineal, caesarean wound), incontinence, anaemia after haemorrhage and sleep deprivation all worsen mood and should be treated in their own right.	FBC/ferritin, TFTs; birth debrief

Key phrases that score

"Have you had any thoughts of harming yourself, or that the baby would be better off without you?" — direct, compassionate self-risk assessment.

"Many mums get frightening, unwanted thoughts about the baby that horrify them — have you? The distress they cause you is actually reassuring." — interprets ego-dystonic thoughts correctly.

"Telling me how you feel will not lead to your baby being taken away." — unlocks disclosure.

Deductions

Not asking about self-harm/suicide and thoughts about the baby

Step 2

Triage — Emergency (Psychosis / Suicide) · Urgent · Routine

▲collapse

The triage hinge in perinatal mental health is risk: postpartum psychosis and active suicidality/infanticidal intent are emergencies needing same-day specialist assessment; severe depression needs same-day mental health assessment and high-risk histories need urgent perinatal input; and mild–moderate PND/anxiety is managed in primary care with the health visitor and talking therapies. Priya is moderate PND with ego-dystonic thoughts and no psychosis — but her passive suicidal ideation ("better off without me") needs a structured risk assessment today and same-day discussion with the perinatal (or crisis) team, then active primary-care management with a clear safety-net.

Triage rationale

"You're not safe to be left struggling alone, but you're also not in crisis — there's no sign of the severe illness that needs hospital. So we'll treat this actively here, bring in your health visitor and the perinatal team, and I'll give you a clear plan for if things get worse."

Step 3

Assessment — Mental State · Risk Formulation · Mother–Infant · Physical

▲collapse

"Examination" here is the mental state assessment and risk formulation, an observation of the mother–infant interaction, and a check for physical contributors. The risk formulation — to self, to the baby, and from others — is the document that drives every subsequent decision.

🧠 Mental state & risk

Domain	What to assess
Appearance/behaviour	Self-care, engagement, agitation/retardation, rapport.
Mood & affect	Low/labile/elated; range; reactivity.
Thought	Guilt/worthlessness; intrusive thoughts (ego-dystonic vs delusional); content about the baby.
Perception & insight	Hallucinations/delusions (psychosis); insight preserved (PND) vs lost (psychosis).
Risk formulation	To self (ideation/plan/intent/protective factors), to baby (intent/capacity to care), from others (abuse).

👶 Infant & physical

Check	Why
Mother–infant interaction	Bonding, responsiveness, warmth; infant feeding/growth and welfare.
Infant safety/welfare	Safeguarding assessment; other children; home situation.
Physical contributors	Thyroid (postpartum thyroiditis), anaemia, pain, sleep deprivation.
Screening tools	Whooley questions; EPDS for severity/monitoring (note item 10 — self-harm).

🎓 SCA Checkpoint — Step 3TasksGlobal Skills

Demonstrating the formulation

"From what you've told me: your mood has been low for a month with lots of guilt, you've had frightening thoughts that distress you but you'd never act on, and there's no sign of losing touch with reality. I'd put the risk to you and the baby as low right now — but I want a clear plan in case that changes."

Deductions

Not quantifying severity or documenting risk
Missing thyroid/anaemia as contributors

Step 5

Diagnosis — Blues · PND · Anxiety/OCD/PTSD · Psychosis

▲collapse

Name the condition and its severity, and explicitly state the risk formulation — because the same symptom (a thought about harm) means completely different things in PND versus psychosis.

Diagnosis	Discriminating features	Urgency
Baby blues	Days 3–10, tearful/labile, transient, function preserved, resolves by 2 weeks.	Routine
Postnatal depression	Persistent (>2 weeks) pervasive low mood, guilt, anhedonia, impaired function/bonding, ego-dystonic intrusive thoughts (Priya).	Active Rx
Perinatal anxiety / OCD	Excessive worry, panic, intrusive thoughts with checking/avoidance; often coexists with depression.	Active Rx
Birth-related PTSD	Re-experiencing, avoidance, hyperarousal after traumatic birth.	Therapy
🚩 Postpartum psychosis	Rapid onset, mania/confusion, delusions (often about baby), hallucinations, lost insight.	EMERGENCY

🚩 The discipline — the same thought, two very different illnesses

The pivotal clinical judgement is the nature of a thought about harm. An ego-dystonic intrusive thought — unwanted, distressing, recognised as wrong, with no intent and preserved insight — is a feature of postnatal depression/anxiety/OCD and is reassuring in its very distress; it should be normalised and treated, not panicked over. A thought driven by a delusion or command hallucination, or with intent, or with lost insight, is postpartum psychosis — an emergency. For Priya, the formulation is moderate postnatal depression with ego-dystonic intrusive thoughts, no psychosis, current risk low but with a family history of probable postpartum psychosis warranting vigilance.

🎓 SCA Checkpoint — Step 5Tasks

Explaining it plainly

"What you have is postnatal depression — common, and very treatable. The frightening thoughts are part of it, not a sign you'll act on them. You're not losing your mind, and you're not a danger to your baby — but we'll keep a close eye and you've got a clear plan."

Deductions

Confusing intrusive thoughts with psychosis (or vice versa)
Not stating an explicit risk formulation

Step 6

Referral — Crisis/MBU · Perinatal Team · Health Visitor · Safeguarding

▲collapse

Referral is driven by the risk formulation: emergency psychiatric assessment and Mother & Baby Unit for psychosis or acute risk; the perinatal mental health team for severe, complex or high-risk cases; the health visitor as a core partner in all; and safeguarding where the infant's welfare is in question.

Referral	Who / when	Urgency
🔴 Crisis / perinatal psychiatry / MBU	Postpartum psychosis, active suicidality, intent to harm baby, severe depression. Admission keeps mother and baby together (Mother & Baby Unit).	Same day
Perinatal mental health team	Moderate–severe PND/anxiety, complex cases, medication in pregnancy/breastfeeding, and high-risk histories (bipolar, postpartum psychosis).	Urgent / soon
Talking therapies (NHS Talking Therapies/perinatal)	Mild–moderate depression/anxiety/OCD/PTSD — often first-line; perinatal-specific where available.	Routine
Health visitor	Core support for all — monitoring, practical help, infant welfare, listening visits.	Routine
Safeguarding / social care	Where infant or other children's welfare is a concern, or domestic abuse.	Per local pathway

🎓 SCA Checkpoint — Step 6Tasks

Framing MBU positively

"If anyone ever does need hospital care for this, there are special units where mum and baby stay together — you would never be separated from your baby. But you're not at that point; we'll support you at home."

Deductions

Not escalating psychosis or acute risk same-day

Step 7

Management — Talking Therapy · Medication & Breastfeeding · Support · Safety-Net

▲collapse

Management is stepped to severity: support and talking therapy for mild–moderate illness, antidepressants (sertraline commonly, even when breastfeeding) where moderate–severe or unresponsive, the health visitor and social support throughout, and a clear, explicit safety-net for escalation. The guiding principle is not to withhold effective treatment from a breastfeeding mother out of unfounded medication fears.

7A — Address the patient's expectation first: validate → explain → negotiate

🤝

Priya has two unspoken expectations — that honesty will cost her the baby, and that treatment will mean stopping breastfeeding. Answer both before offering any plan

Validate — name the fear and the wish

Priya expects judgement, and possibly the involvement of social services, because she has admitted to frightening thoughts. She also wants to keep breastfeeding and fears medication will harm the baby through her milk. Both are reasonable given what she knows. Naming them out loud, before discussing treatment, shows that you have heard what she has not quite said, and it takes the edge off her fear.

"I suspect two things might be worrying you: that telling me about those thoughts means someone will take your baby, and that getting help means giving up breastfeeding. Can I answer both of those honestly before we talk about anything else?"

Explain — share the reasoning plainly

Ego-dystonic intrusive thoughts are a recognised feature of perinatal depression and anxiety. They do not mean she is dangerous, and on their own they are not a safeguarding trigger. Involving the health visitor and perinatal services is about supporting the family. Breastfeeding does not rule out treatment: psychological therapy is first-line for mild to moderate illness, and where an antidepressant is needed, sertraline passes into breast milk in only small amounts. Leaving depression untreated carries its own risks for mother and baby.

"The thoughts you've described are something many mums with postnatal depression get. They frighten you precisely because you'd never act on them. That's not a reason to worry about your baby's safety; it's a reason to get you well. And you won't have to choose between getting better and breastfeeding."

Negotiate — a concrete plan she has chosen

Offer a menu rather than a prescription: talking therapy (with rapid perinatal access), health visitor listening visits, practical support, and sertraline if she wants to add it now or if symptoms don't improve. Given her moderate symptoms and family history, discuss the case with (or refer to) the perinatal mental health team. She should leave with a written crisis plan and a review date within about 2 weeks, sooner if she starts medication.

"Here's what I'd suggest, and you tell me what feels right: a referral for talking therapy, your health visitor coming to see you, and — if you'd like — a tablet that's commonly used while breastfeeding. I'll see you again in a week or two, and I'll give you the numbers to ring any time you feel unsafe."

Key principle: in perinatal mental health, the patient's biggest fear is usually about the baby, not herself. If that fear is not addressed at the start, she may say what she thinks you want to hear and avoid follow-up. A mother who trusts that disclosure leads to help will tell you when things get worse, and that is the most effective safety-net there is.

7B — Why treatment matters: goals tailored to this patient

Treatment goals for Priya

Safety: no escalation to suicidal intent; crisis plan known to Priya and partnerEarly warning: any manic/psychotic symptom acted on the same day Remission of depression: EPDS trending down at each reviewIntrusive thoughts understood and less distressing Bonding and infant wellbeing supported (HV, mother–infant work)Breastfeeding continued if that is her choice Sleep, nutrition and physical contributors (iron, thyroid) addressedPlan for future pregnancies documented

Motivational language — tailored to Priya

"Getting you well is one of the best things you can do for your baby. Babies need their mum to feel like herself. Accepting help isn't selfish; it's part of looking after her."

"Postnatal depression is one of the most treatable conditions I see. Most mums who get the right support feel very different within a few months, and look back on this as an illness they recovered from, not as a sign of the mother they are."

Leading cause

Suicide is the leading cause of maternal death between 6 weeks and 1 year after the end of pregnancy (MBRRACE-UK 2025)

Item 10

EPDS self-harm question — ask it aloud and act on any positive answer, whatever the total score

7C — Non-medication management: mechanism + evidence + tailored advice

NICE CG192 places psychological interventions at the centre of care for mild to moderate perinatal depression and anxiety, and asks that they are started quickly (the guideline's aim is assessment within 2 weeks of referral and psychological intervention within 1 month of that assessment). Practical, social and relational support comes alongside therapy, not instead of it. For Priya, every item below is compatible with breastfeeding and can start this week.

💬

Psychological therapy (CBT / IPT)

Target: referral today; perinatal priority access

Mechanism

CBT targets the thinking patterns behind the guilt and hopelessness ("I'm a terrible mother") and the way intrusive thoughts are interpreted. Interpersonal therapy works on role transition — the move into motherhood — and on relationships and support. For intrusive harm thoughts, exposure-based CBT reduces the checking and avoidance that keep them going.

Practical

NHS Talking Therapies services in England prioritise pregnant and postnatal women, and many accept self-referral. Where symptoms are subthreshold to moderate, facilitated self-help is an option; for moderate to severe depression, high-intensity CBT (or IPT) is appropriate. Check that the service can see her with the baby present, or that childcare is possible.

NICE CG192: offer psychological intervention for mild to moderate perinatal depression and anxiety

🏠

Health visitor partnership

Target: HV contacted within days, with consent

Mechanism

The health visitor sees mother and baby at home. She can offer listening visits, repeat the EPDS, watch how feeding and bonding are going, and pick up deterioration earlier than a GP appointment would. Continuity reduces isolation and builds a trusting relationship that makes disclosure easier.

Practical

With Priya's consent, phone or task the health visitor the same day, share the risk formulation and the crisis plan, and agree who reviews what and when. Explain to Priya that this is support, not surveillance, and say it explicitly, because she fears exactly the opposite.

Joint GP–HV working is a core part of perinatal care pathways

😴

Protecting sleep

Target: one protected block of sleep most nights

Mechanism

Severe sleep loss worsens mood, anxiety and intrusive thoughts. In women at risk of bipolar disorder or postpartum psychosis, sleep disruption is a recognised trigger for relapse. Insomnia even when the baby is asleep is a symptom to track, and a sudden reduced need for sleep is a warning sign of mania.

Practical

Plan with the couple: the partner takes one night feed (expressed milk or formula top-up if she chooses) so she gets a 4–5 hour block. Share night duties at weekends and make use of nap opportunities. Avoid sedative hypnotics while breastfeeding or co-sleeping unless a specialist advises them. Give safe-sleep advice for the baby.

Protected sleep is a standard relapse-prevention step in perinatal psychiatry

🤱

Mother–infant relationship support

Target: bonding assessed and supported at each review

Mechanism

Depression can blunt a mother's responsiveness to her baby, and she may then read the baby's behaviour as rejection, which deepens the guilt. Interventions that focus on the relationship (such as video-interaction guidance or parent–infant psychotherapy, where available) help her see the baby's cues and her own competence.

Practical

Point out specific moments of connection in the room ("she's watching your face"). The health visitor or local parent–infant service can offer structured work. Baby massage and parent–baby groups offer contact with other parents, but only if she feels able to go.

NICE CG192 recommends considering extra help with the mother–baby relationship where there are difficulties

🤝

Peer and voluntary support

Target: one peer contact signposted today

Mechanism

Hearing other mothers describe the same thoughts and guilt is powerfully normalising, and it reduces the shame that drives silence. Peer support also eases isolation, a recognised risk factor, especially for first-time mothers living far from family.

Practical

Signpost to national perinatal charities (for example PANDAS Foundation, and Action on Postpartum Psychosis for women with a family history of postpartum psychosis) and to local peer groups. Include the partner: charities also run support for fathers and partners.

Peer support is an adjunct that improves engagement; it does not replace treatment

🍎

Physical recovery and the basics

Target: FBC/ferritin and TFTs where features suggest (her exhaustion does); pain treated

Mechanism

Postpartum iron deficiency, postpartum thyroiditis, unrelieved pain and poor nutrition all cause fatigue and low mood and make depression harder to treat. Gentle physical activity has a modest antidepressant effect and gives the day some structure.

Practical

Check FBC, ferritin and TFTs; treat any deficiency. Ask about perineal or wound pain and about continence. Encourage regular meals and fluids (especially while breastfeeding), and short daily walks with the pram, framed as something for her rather than another task to fail at.

Treating physical contributors often lifts energy within weeks

7D — Prescribing guide: stepped care under NICE CG192 — therapy, medication and breastfeeding

💬 Psychological & support

Element	Detail
Talking therapy	Guided self-help/CBT for mild–moderate; perinatal-specific therapy where available; first-line for many, especially if she prefers to avoid medication.
Health visitor	Listening visits, monitoring, practical support, infant welfare — a core part of the plan.
Social support	Partner involvement, practical help, sleep, peer support, addressing isolation/abuse.
Normalise & educate	Explain the illness, the intrusive thoughts, and recovery — reduces guilt and improves engagement.

💊 Medication & safety-net

Element	Detail
Antidepressant	For moderate–severe or unresponsive: sertraline commonly used in breastfeeding (low milk transfer); discuss risks/benefits; don't withhold effective treatment for breastfeeding alone.
If already on treatment	Optimise; avoid abrupt changes; perinatal advice for complex regimens; never stop lithium/abruptly switch without specialist input.
High-risk history	Bipolar/postpartum psychosis history → perinatal psychiatry, vigilance, care plan.
Safety-net	Explicit: what to do and who to call if mood worsens, thoughts of harm intensify, or any psychotic features emerge — including out-of-hours/crisis numbers; involve partner in the plan.
Review	Early and regular review (and EPDS tracking); close the loop with the health visitor/perinatal team.

NICE CG192 does not set out a drug "ladder". It asks for a shared decision that weighs the risks of treatment against the risks of untreated illness for both mother and baby, using the latest safety data (in the UK: UKTIS for pregnancy, and the Specialist Pharmacy Service for breastfeeding). In practice, primary care follows the stepped approach below. Anything beyond an SSRI in a well-screened woman — mood stabilisers, antipsychotics, complex regimens, or any history of bipolar disorder or psychosis — goes through perinatal psychiatry.

Step / severity	What to offer (NICE CG192, with NICE NG222 for depression)	Prescribing notes
Baby bluesDays 3–10, resolving	Reassurance, explanation, practical support and rest. Arrange a check (HV or GP) if symptoms have not resolved by about 2 weeks.	No medication
Subthreshold / mild–moderate depression or anxiety	Facilitated self-help (CBT-based materials with support) or a high-intensity psychological intervention, depending on severity and history. Health visitor listening visits, peer support, and treatment of any physical contributors.	CG192: consider an antidepressant (TCA, SSRI or SNRI) if she has a past history of severe depression. Otherwise a shared decision if therapy is declined or has not helped
Moderate–severe depressionPriya	Offer a high-intensity psychological intervention (e.g. CBT); an antidepressant (SSRI, TCA or SNRI) if she understands the risks and prefers medication, declines therapy, or has not responded to it; and the two combined if response to either alone is absent or partial. Discuss with or refer to the perinatal mental health team, given the family history and the severity.	Breastfeeding: sertraline commonly used (low milk transfer). Dose per SPC and local formulary: 50 mg once daily, increased in 50 mg steps at intervals of at least a week if needed; max 200 mg daily
Already on an effective antidepressant	Do not switch or stop abruptly because of pregnancy or breastfeeding. Review the balance of risks. Switching a drug that works to one that is "safer on paper" can lead to relapse, and the baby is then exposed to two drugs.	Seek UKTIS/SPS or perinatal pharmacy advice if unsure
Bipolar disorder, previous postpartum psychosis, or severe mental illness	Specialist perinatal psychiatry. Preconception and antenatal care planning; a written plan for late pregnancy and the first postnatal weeks; mood stabiliser or antipsychotic decisions made by specialists.	GP: don't start antidepressant monotherapy if bipolar is suspected; don't stop lithium or antipsychotics abruptly
Postpartum psychosis / severe risk	Emergency: assessment by a secondary mental health service (preferably perinatal) within 4 hours of referral (CG192). Usually Mother and Baby Unit admission; medication initiated in secondary care.	Same day — do not start treatment in primary care and send home

Valproate — do not use in women and girls of childbearing potential for mental illness

NICE CG192: do not offer valproate for acute or long-term treatment of a mental health problem in women and girls of childbearing potential, unless other options are ineffective or not tolerated and the pregnancy prevention programme is in place.
Babies exposed in utero have around an 11% risk of major congenital malformations and up to a 30–40% risk of neurodevelopmental disorders (figures quoted by the MHRA).
MHRA (from 31 January 2024): valproate must not be started in anyone, male or female, under 55 unless two specialists independently consider and document that no other effective or tolerated treatment exists, or that the reproductive risks do not apply. Women already on it need an annual specialist review with a signed risk acknowledgement form and highly effective contraception under the pregnancy prevention programme.
GP role: never stop valproate abruptly in a woman who discovers she is pregnant — arrange urgent specialist review; ensure contraception and the annual review are in place for women who continue it.

Lithium — specialist decisions only

Lithium in pregnancy carries a small increased risk of fetal cardiac malformations. Stopping it, especially abruptly, sharply raises the risk of bipolar relapse. Whether to continue is a specialist decision made with the woman, ideally before conception.
NICE CG192: if lithium is continued in pregnancy, check plasma levels every 4 weeks, then weekly from 36 weeks, and within 24 hours of childbirth; make sure she drinks enough fluid; plan birth in an obstetric unit with fluid balance monitored.
Breastfeeding: NICE CG192 advises women taking lithium not to breastfeed, because lithium passes into milk and can reach toxic levels in the infant.
GP role: flag every woman of childbearing potential on lithium for preconception advice; never stop it without specialist input; recognise toxicity (vomiting, diarrhoea, tremor, confusion) as an emergency, especially around birth and with dehydration.

SSRIs in pregnancy — the balanced conversation

Most SSRIs have not been linked with a major overall increase in malformations. UKTIS monographs give the current evidence for each drug and should be used for individual counselling. Paroxetine has been associated with cardiac malformations in some studies and is generally not a first choice to start in pregnancy.
Late-pregnancy exposure is linked with transient neonatal adaptation symptoms (jitteriness, feeding difficulty) and a small increased absolute risk of persistent pulmonary hypertension of the newborn. Tell the maternity team so the baby can be observed after birth.
MHRA Drug Safety Update (January 2021): SSRI/SNRI use in the month before delivery may cause a small (less than 2-fold) increase in the risk of postpartum haemorrhage. Take this into account alongside other bleeding risks; it is not a reason to stop an effective antidepressant.
Untreated depression in pregnancy is associated with poorer self-care, preterm birth and postnatal depression. The risk of doing nothing belongs in the same conversation.

SSRIs in breastfeeding — what the SPS guidance says

The NHS Specialist Pharmacy Service lists sertraline and paroxetine as the SSRIs of choice during breastfeeding. Both have shorter half-lives and pass into milk in smaller amounts than other SSRIs.
Fluoxetine (long half-life, active metabolite) and citalopram produce higher infant levels; they are generally not first choices to start while breastfeeding, although a woman already well on one should not be switched without advice.
Ask about the baby's age and health: premature, low-birth-weight or unwell infants need more caution. Advise the mother to watch for irritability, poor feeding, excessive sleepiness or poor weight gain, and to report these promptly.
If she started an SSRI in pregnancy and wants to breastfeed, continuing the same drug usually avoids a second exposure for the baby.

7F — Drug reference cards: perinatal psychotropics in primary care

Sertraline (SSRI) — usual choice when breastfeeding

Sertraline 50 mg / 100 mg tablets

First-line where an antidepressant is chosenDose per SPC and local formulary (usually 50 mg OD to start)

✓ Prefer when

Moderate–severe postnatal depression or anxiety in a breastfeeding mother. SPS lists it as an SSRI of choice in breastfeeding because of low milk transfer

Perinatal OCD with intrusive harm thoughts, alongside CBT with exposure and response prevention

Antenatal depression needing medication, after a UKTIS-informed discussion

✗ Avoid / caution

Suspected bipolar disorder or a history of mania/hypomania — risk of switching into mania; refer to perinatal psychiatry instead of starting monotherapy

MAOI within 14 days

Bleeding risk (anticoagulants, antiplatelets, bleeding disorders); late pregnancy — small PPH risk (MHRA DSU Jan 2021); epilepsy; hepatic impairment; premature or unwell infant (more caution with breastfeeding)

⚠ Side effects

Nausea, GI upset, headache, sleep change, early jitteriness or anxiety, sexual dysfunction, hyponatraemia (rare in this age group). Suicidal thinking and agitation can increase early in treatment, especially under 25s — review early

Discontinuation symptoms if stopped abruptly — taper when stopping

🔬 Monitor

Review within 1–2 weeks of starting (mood, risk, side effects, the baby's feeding and behaviour). EPDS/PHQ-9 at each review. Assess response at around 4 weeks at an adequate dose before changing. Usually continue for at least 6 months after remission, reviewed regularly (NICE NG222)

💬 Counselling

"This is the antidepressant most often used while breastfeeding — only a very small amount gets into your milk. It usually takes 2 to 4 weeks to start helping, and you may feel a bit sick or jittery for the first week or so. If you feel worse, more agitated, or have thoughts of harming yourself, contact us straight away. Please don't stop it suddenly — we'll plan any reduction together."

SCA: state that she can keep breastfeeding, give the reason (low milk transfer), mention monitoring the baby, and make it her choice. Withholding an effective antidepressant because she is breastfeeding is a recognised examiner deduction.

Other SSRIs and antidepressants — know the perinatal caveats

Paroxetine · Fluoxetine · Citalopram / escitalopram · Mirtazapine · TCAs

Case-by-caseDose per SPC and local formulary

✓ Reasonable when

She is already well on one of these and a change would risk relapse or a second exposure for the baby

Paroxetine: an SPS-listed option in breastfeeding (low milk levels), though not a first choice to start in pregnancy

Previous good response to a specific drug — past response is a strong predictor

✗ Avoid / caution

Fluoxetine — long half-life and active metabolite give higher infant exposure in breastfeeding; not first choice to start postnatally

Paroxetine — associated with cardiac malformations in some studies; avoid starting in the first trimester if alternatives exist; marked discontinuation symptoms

Citalopram/escitalopram — QT prolongation; higher milk transfer than sertraline

TCAs — toxic in overdose; weigh this carefully in a woman with suicidal thoughts and limit supply

⚠ Side effects

Class effects as for sertraline; mirtazapine and TCAs cause sedation and weight gain. Sedation matters for night feeds and safe infant sleep — advise against co-sleeping when sedated

🔬 Monitor

Check the drug-specific UKTIS (pregnancy) or SPS (breastfeeding) guidance before starting or switching. Watch for infant adverse effects, and limit quantities if suicide risk is present

💬 Counselling

"The one you're on is working, and changing it now carries its own risks. I've checked the current safety information, and the safest thing is usually to stay on what's working and keep an eye on you both."

Don't reflexively switch a woman who is well. The skill is weighing relapse risk against drug risk, and saying so.

Lithium — specialist-led

Lithium carbonate (prescribe by brand) · Lithium citrate

Specialist onlyDose per specialist / serum level

✓ Specialist may continue when

Bipolar disorder with a high risk of relapse, where the benefit of continuing outweighs the small fetal cardiac risk. The decision is made with the woman, ideally before conception

✗ Avoid / caution

Never stop abruptly — rebound relapse risk, highest in the postpartum period

Breastfeeding — NICE CG192 advises women on lithium not to breastfeed

Dehydration, vomiting, NSAIDs, ACE inhibitors/ARBs and diuretics raise levels; renal and thyroid disease

⚠ Toxicity — an emergency

Coarse tremor, vomiting, diarrhoea, ataxia, confusion, drowsiness. Levels shift rapidly around delivery as fluid balance and renal clearance change

🔬 Monitor

NICE CG192 (if continued in pregnancy): plasma lithium every 4 weeks, then weekly from 36 weeks, and within 24 hours of childbirth; adequate fluid intake; birth in an obstetric unit. Usual renal and thyroid monitoring per shared-care protocol

💬 Counselling

"Please don't stop your lithium because you're pregnant or planning to be — stopping suddenly is one of the biggest triggers for becoming very unwell after a baby. Let's get you an appointment with the perinatal team so you can decide together."

The GP's job is to flag, refer and not stop. Suggesting that she stop lithium herself, or stopping it yourself, would be a serious safety error.

Valproate — do not use for mental illness in women of childbearing potential

Sodium valproate · Valproic acid · Semisodium valproate

Contraindicated unless PPP + specialistsNot a primary-care initiation

✗ Do not use

NICE CG192: do not offer valproate for a mental health problem in women and girls of childbearing potential unless other options have failed or are not tolerated and the pregnancy prevention programme is in place

MHRA (January 2024): must not be started in patients under 55 unless two specialists independently document that there is no other effective or tolerated treatment, or that the reproductive risks do not apply

Risk to the baby with in-utero exposure: about 11% major malformations and up to 30–40% neurodevelopmental disorders

⚠ If she is already taking it

Confirm highly effective contraception, the annual specialist review and the signed risk acknowledgement form. If she is pregnant, do not stop it abruptly — arrange urgent specialist review the same week

🔬 Monitor

Practice searches for women and girls of childbearing potential on valproate; check the PPP is in place; take a pregnancy test if there is any doubt; issue the patient guide

💬 Counselling

"This medicine can seriously harm a developing baby, so it's only used when nothing else works, and with reliable contraception. If you think you might be pregnant, keep taking it and contact us today — we'll get specialist advice straight away."

Name the MHRA restrictions and the pregnancy prevention programme. Valproate is a common SCA "hidden agenda" in bipolar and epilepsy cases involving women of reproductive age.

Antipsychotics — specialist initiation

e.g. quetiapine · olanzapine · aripiprazole (specialist choice)

SpecialistDose per specialist / SPC

✓ Used by specialists for

Postpartum psychosis, bipolar disorder (acute or prophylaxis), schizophrenia; sometimes as prophylaxis in very high-risk women immediately after birth

✗ Avoid / caution

Do not stop abruptly in a woman who becomes pregnant — seek specialist advice

Gestational diabetes and weight gain (screen glucose); sedation affecting night-time infant care; breastfeeding compatibility varies by drug — check SPS

⚠ Side effects

Sedation, weight gain, metabolic effects, raised prolactin (some agents), extrapyramidal effects

🔬 Monitor

Physical health monitoring per shared care (weight, glucose/HbA1c, lipids); in pregnancy, glucose monitoring per the specialist plan; infant sedation and feeding if breastfeeding

💬 Counselling

"This medicine is helping keep you well. If it makes you very sleepy, let's think about night feeds and safe sleep for the baby — and please don't stop it without talking to your team."

Primary care does not start antipsychotics for suspected postpartum psychosis. Refer the same day; the medication decision belongs to the admitting team.

Benzodiazepines and Z-drugs — generally avoid

Diazepam · Lorazepam · Zopiclone

Avoid in routine careNot recommended

✗ Avoid

NICE CG192: do not offer benzodiazepines to women in pregnancy and the postnatal period, except for short-term treatment of severe anxiety and agitation

Late pregnancy: risk of neonatal sedation and withdrawal ("floppy infant"). Breastfeeding: infant sedation; long-acting agents accumulate

Sedation plus co-sleeping or sofa-sleeping raises the risk of sudden infant death

⚠ Side effects

Sedation, dependence, respiratory depression when combined with alcohol or opioids

🔬 Monitor

If used short-term under specialist advice: shortest course, lowest dose, no co-sleeping, review within days

💬 Counselling

"Sleeping tablets would make it harder for you to wake for the baby and can pass into your milk, so I'd rather we protect your sleep in other ways — like your partner doing a night feed."

Declining a sleeping tablet safely and offering a practical alternative scores; prescribing zopiclone for postnatal insomnia without discussion does not.

7G — Psychosocial impact: identity, relationship, work, driving and safeguarding

🤝

Perinatal illness — the mother who feels she is failing at the one thing she was "supposed" to find natural

Perinatal mental illness strikes at identity, at the couple's relationship and at the family's sense of safety, all at once and at a time of extreme exhaustion. The mother often feels ashamed of being unwell when she is "meant to be happy". The partner may feel helpless or frightened, and the wider family may offer advice that deepens the guilt. A plan that only treats symptoms, without addressing these pressures, is likely to fail.

👤

Identity and the "good mother" ideal

Priya expected motherhood to feel natural and joyful. When it doesn't, she concludes she is defective. Social media and well-meaning relatives reinforce the ideal. Separating the illness from her identity, and explaining that bonding often grows gradually, eases the self-blame that keeps depression going.

"Lots of mums don't feel an instant rush of love, especially when they're unwell — it often grows as you recover. What I can see is a mum who is worried sick about doing right by her baby."

💑

The partner and the relationship

Partners commonly feel shut out, frightened or resentful, and they are at increased risk of depression themselves. Involving him (with Priya's consent) in the explanation, the practical plan and the crisis plan makes him an ally and an early-warning system. It is also a chance to ask how he is coping. Remember that domestic abuse must still be asked about with Priya alone.

"You've clearly been worried about her. The most helpful things you can do are protect some sleep for her, keep her company, and call for help straight away if she seems very different or talks about not being safe. And how are you doing?"

💼

Maternity leave, work and money

Worry about returning to work, reduced income on statutory maternity pay, or self-employed income stopping can all add to depression. If she is not fit to return when leave ends, a fit note can be issued. Signposting to benefits and financial advice (Citizens Advice, health visitor links) is part of management, not an extra.

"Let's not add work to your worries right now — if you're not well enough when your leave ends, we can sort a fit note and a phased return. Is money a worry at the moment?"

🚗

Driving and the DVLA

Mild to moderate depression without significant impairment does not usually need DVLA notification. DVLA guidance says that severe depression with significant memory or concentration problems, agitation, behavioural disturbance or suicidal thoughts means she must not drive and must notify the DVLA, and with an acute psychotic illness (including postpartum psychosis) she must not drive and must notify the DVLA. Sedating medication and extreme sleep deprivation also impair driving with a baby in the car.

"At the moment you're safe to drive as long as you feel alert — but if you're ever so exhausted you can't concentrate, or you're having thoughts of harming yourself, please don't drive, and we'd need to talk about telling the DVLA."

🛡️

Safeguarding — support, not punishment

Safeguarding is about the welfare of the baby, any other children and the mother as an adult at risk. Ego-dystonic intrusive thoughts with no intent, and a mother who is caring well for her baby, do not in themselves trigger a referral to children's social care. A referral is needed when the baby's safety or care is compromised, when there is intent or psychosis, when there is domestic abuse with children in the household, or when she cannot care for the baby. If you are unsure, discuss with the practice safeguarding lead, and be open with the family where this is safe.

"My job is to keep you and your baby well together. If I were ever worried about her safety, I'd tell you honestly and we'd get extra support in — the aim is always help, not taking her away."

🌍

Culture, language and extended family

Cultural expectations about the postnatal period, the role of grandparents, and stigma around mental illness vary widely and can help or hinder recovery. Use a professional interpreter when needed, never the partner or a relative, for mental health and risk questions. Ask what support the extended family can offer, and whether anyone is making things harder.

"In some families there's a lot of support after a baby, and in others it can feel like a lot of pressure. What's it like in your family? Is there anyone who makes you feel better — or worse?"

7H — Follow-up schedule

Today — Risk plan, referrals and a named contact

Document the risk formulation (to self, to the baby, from others). Refer to psychological therapy; contact the health visitor with consent; discuss with the perinatal mental health (or crisis) team the same day, given her passive suicidal ideation, the moderate severity and her mother's probable postpartum psychosis, and refer as advised. Bloods (clinically directed, given her exhaustion): FBC, ferritin, TFTs. Written crisis plan with numbers (practice, NHS 111 mental health option, local crisis line, 999), shared with her partner if she agrees. If starting sertraline, give a limited supply and a review date.

Crisis plan writtenHV + perinatal team informed

1–2 Weeks — Early review (sooner if she has started medication)

Re-assess mood, suicidal ideation and intrusive thoughts; re-screen for manic or psychotic symptoms (family history); side effects; the baby's feeding, sleep and behaviour if she is breastfeeding on an SSRI. Repeat the EPDS and ask item 10 aloud. Check that therapy and HV contact have started and that blood results have been acted on.

Risk + psychosis re-screenSSRI tolerance + infant check

4–6 Weeks — Response check

If on sertraline, is she on an adequate dose with some response? If there is no meaningful improvement at an adequate dose, increase the dose per SPC or discuss with the perinatal team; don't carry on unchanged. Therapy engagement, sleep, bonding and support. Ask about domestic abuse again at a moment alone. Liaise with the HV about how things are at home.

EPDS trendEscalate if no response

3–6 Months — Consolidation

Aim for remission. Continue the antidepressant, usually for at least 6 months after remission with regular review (NICE NG222), and when stopping, taper gradually rather than abruptly. Plan for return to work and a fit note if needed. Discuss contraception and the spacing of any future pregnancy. Record the episode clearly in the notes as a perinatal depressive episode, with the family history.

RemissionContraception + planning

Future pregnancy — Preconception and booking

A previous perinatal depression, plus a family history of probable postpartum psychosis, means higher risk next time. Offer preconception advice (medication plan, early referral). Tell the midwife at booking so perinatal mental health can be involved. Agree a written plan for late pregnancy and the first postnatal weeks, including early warning signs and whom to call.

⚠ Three scenario-specific phrases — use these verbatim

What to document

Risk formulation: "Passive ideation ('better off without me'), no plan or intent; ego-dystonic intrusive harm thoughts, no intent, insight preserved; no psychotic or manic features; protective factors: baby, partner."

Family history: "Mother had postnatal 'breakdown', probably postpartum psychosis — raised risk; perinatal team informed; partner briefed on the warning signs."

Safeguarding reasoning: "Infant well cared for; intrusive thoughts ego-dystonic; no current indication for a children's social care referral; HV involved; to be reviewed at each contact."

Medication discussion: "Risks and benefits of sertraline in breastfeeding discussed (SPS guidance), including the risks of untreated depression; patient's choice recorded; bipolar screen negative."

Crisis plan: "Written crisis numbers given; same-day action for psychotic symptoms, suicidal intent or a change in thoughts about the baby; partner included with consent."

Domestic abuse: "Enquiry made with the patient alone on [date]" — or "not yet possible; plan to ask alone at next contact."

Fear of losing the baby answered first; guilt named as a symptom; plan built from her choices; partner involved with consent; hope conveyed

🟠

Reassurance given but generic; the decision is largely the doctor's; partner either ignored or allowed to speak for her

🔴

Alarm shown at her disclosure; judgemental language; she leaves more frightened than she arrived

No plan, no follow-up, no crisis route

💬 Key phrases

😟 The baby won't be taken

"Telling me this doesn't mean your baby will be taken away. It means we can get you the right help, with your baby, at home."

🧠 Intrusive thoughts

"These thoughts are your mind's alarm system going off too often. They upset you because they're the opposite of what you want, and that's exactly why they're not dangerous."

🍼 Breastfeeding and medication

"You don't have to choose between getting better and breastfeeding. Sertraline is the medicine most often used by breastfeeding mums — only tiny amounts get into your milk."

🤝 The guilt

"Feeling like a terrible mother is one of the symptoms of this illness, not a fact about you."

🚨 Psychosis safety-net

"If you stop needing sleep, feel sped up or confused, or have strange ideas — that's a same-day emergency. Your partner knows the signs too."

⛔ Danger zone — common pitfalls in perinatal mental health

✗

Treating ego-dystonic intrusive thoughts as a psychosis or safeguarding emergency→ Explore intent, insight and distress. If the thoughts are unwanted, resisted and horrifying to her, normalise them and treat the depression or OCD.

✗

Missing early postpartum psychosis because it fluctuates or she seems "fine" today→ Ask about sleep need, elation, confusion and odd beliefs; take the partner's account seriously; refer the same day if you have any doubt.

✗

Starting an antidepressant without screening for bipolar disorder→ Ask about previous highs and the family history; refer to perinatal psychiatry if bipolar is suspected.

✗

Telling a mother to stop breastfeeding, or withholding treatment, because of medication fears→ Use SPS guidance: sertraline is commonly used; the risks of untreated depression go in the same conversation.

✗

Stopping lithium, valproate or antipsychotics abruptly when a woman becomes pregnant→ Continue and get urgent specialist advice; relapse risk after abrupt withdrawal is high.

✗

Asking about domestic abuse in front of the partner→ Ask only when she is alone; plan an opportunity if you can't do it today.

✗

Accepting "better off without me" at face value, or accepting a denial of suicidal thoughts at face value→ Explore passive ideation directly: plans, intent, method, protective factors — and revisit it at every review.

✗

Forgetting the physical contributors→ Check FBC, ferritin and TFTs when fatigue or other features suggest anaemia or thyroid disease; treat pain and anaemia.

🎓 SCA Checkpoint — Step 7TasksRelating to OthersGlobal Skills

A plan that scores

"Here's the plan: talking therapy, your health visitor closely involved, and — if you'd like — an antidepressant called sertraline that's considered one of the safer options while breastfeeding. I'll see you again soon, and here's exactly who to call, day or night, if things get worse or you have any frightening change."

Deductions

Withholding an antidepressant solely because she is breastfeeding
No explicit safety-net / crisis plan for escalation or psychosis
Not involving the health visitor/partner

"Sorry, I'm here about the baby's feeding really… (tearful) …I don't know, I just don't feel like myself. I think I'm just not very good at this."

Who you are

Priya Sharma, 31, first baby, now 7 weeks old. You booked the appointment "about feeding" because you couldn't bring yourself to say the real reason. For about 4 weeks you've felt persistently low, can't sleep even when the baby does, don't enjoy anything, barely eat, and feel crushing guilt that you're "a terrible mother." You've thought "the baby would be better off without me," though you don't have a plan to harm yourself. You are breastfeeding and very anxious about taking any medication. If the doctor is warm, patient and explicitly non-judgmental, you will — with great difficulty — admit you keep getting horrible intrusive thoughts of the baby being harmed, which terrify and disgust you; you would never act on them and they make you feel like a monster. You have told no one. You are NOT confused, elated, or hearing/seeing things, and you know these thoughts are your own. Your mum had a serious breakdown after you were born.

Hidden concerns (reveal if explored)

Fear of losing the baby (main): you're terrified that admitting the thoughts means social services will take your baby. This is why you've hidden it. Explicit reassurance changes everything.

Shame: you feel like a failure and a bad person. Compassion and normalising help hugely.

Medication/breastfeeding: you're scared medication will harm the baby through your milk and don't want to stop breastfeeding.

Clinical details if asked

Low mood ~4 weeks, persistent, worse in mornings; anhedonia; poor sleep and appetite; profound guilt
Passive thoughts "better off without me"; no active suicidal plan or intent; some protective factors (the baby, your partner)
Ego-dystonic intrusive thoughts of harm to baby — distressing, unwanted, no intent; you know they're wrong
No mania, no confusion, no delusions, no hallucinations; insight preserved
No past psychiatric history; mother had a postnatal "breakdown" (possibly psychosis)
Supportive partner; no domestic abuse; birth was okay (no trauma); breastfeeding established

Reactions at key moments

On gentle risk questions: initially hesitant; opens up if reassured and not judged.
On disclosing intrusive thoughts: very ashamed; hugely relieved when told these are common and don't mean you'll act.
On "baby won't be taken": visible relief; becomes much more engaged.
On sertraline: reassured if told it's considered one of the safer options while breastfeeding and the decision is yours.
Challenge line: "Please don't tell anyone about the thoughts — they'll take her away from me, won't they?"

"I've never told anyone this because I was so scared… if I tell you about the thoughts I get, you won't take my baby away, will you?"

Resolution: Priya is helped if the GP: (1) creates a warm, non-judgmental space and reassures her the baby won't be taken away for being honest; (2) conducts a full, sensitive risk assessment (self and baby) and excludes postpartum psychosis; (3) correctly interprets her intrusive thoughts as ego-dystonic (a feature of PND, not psychosis) and normalises them; (4) diagnoses postnatal depression and explains it compassionately; (5) offers talking therapy and discusses sertraline as a breastfeeding-compatible option without withholding treatment; (6) involves the health visitor/perinatal team, flags the family history, and gives an explicit crisis safety-net. She disengages and stays silent if she feels judged, or if her fear of losing the baby is not addressed.

Perinatal Mental Health — Consultation Playbook

Safe space · risk to self & baby · read the thoughts right · don't withhold treatment

▼expand

🎯 The three pivots that pass this case

1 · Risk & psychosis

Always ask about self-harm AND thoughts about the baby; actively exclude postpartum psychosis (an emergency).

2 · Read the thoughts

Ego-dystonic intrusive thoughts (distressing, no intent, insight intact) = PND, normalise. Delusional/command/intent = emergency.

3 · Treat & support

Don't withhold sertraline for breastfeeding; involve HV/perinatal team; reassure the baby won't be taken; explicit crisis safety-net.

⛔ Don't skip the risk assessment (self + baby) · Don't miss postpartum psychosis, or over-react to ego-dystonic intrusive thoughts · Don't withhold effective treatment purely because she's breastfeeding · Don't forget the health visitor, perinatal team and an explicit crisis plan · Address the fear that the baby will be taken away

Baby blues (days 3–10, resolving) ≠ postnatal depression (>2 weeks, pervasive, impairing) · Always assess risk to self AND baby · Postpartum psychosis (rapid onset, mania/confusion/delusions/hallucinations) = emergency → same-day assessment, MBU · Ego-dystonic intrusive thoughts of harm are common in PND/anxiety/OCD — normalise; delusional/command thoughts or intent = emergency · Sertraline commonly used in breastfeeding — don't withhold effective treatment · Personal/family bipolar or postpartum psychosis = high risk · Involve the health visitor and perinatal team; explicit crisis safety-net

Teaching clinicians why each step matters — not just what to do · Always consult current NICE CG192, MHRA Drug Safety Updates and local perinatal pathways · Clinical judgement takes precedence over any framework
