CMPA & Infant Reflux
Red Flags — immediate escalation; these are NOT CMPA until proven otherwise
| Red flag | Why dangerous | Action |
|---|---|---|
| Bilious (green/yellow) vomiting | Bilious vomiting in an infant: intestinal obstruction until proven otherwise — pyloric stenosis (non-bilious); malrotation with volvulus (bilious; surgical emergency); intussusception (with intermittent pain; redcurrant jelly stool). Bilious vomiting is not a feature of CMPA or simple GOR — it always requires same-day hospital assessment. Note: green watery STOOLS (as in Priya) are different from bilious VOMIT and are a CMPA feature. Do not confuse the two. | 999 or A&E now — surgical emergency until proven otherwise |
| Blood in vomit (haematemesis) | Blood in vomit: oesophagitis from severe GORD; Mallory-Weiss tear from forceful vomiting; rarely — bleeding disorder or vascular malformation. In the context of CMPA: oesophagitis from severe reflux may cause blood-streaking. Any haematemesis in an infant requires same-day assessment — it is a marker of severity that changes management from GP-led to hospital-led. | Same-day A&E assessment — needs endoscopy and specialist assessment |
| Apnoea or colour change during feeds | Apnoea during or after feeds: aspiration from severe GOR (laryngospasm reflex); cardiac arrhythmia; neurological (seizure). In the CMPA context: anaphylaxis can present with stridor and apnoea in IgE-mediated cases. Any episode of apparent life-threatening event (ALTE) or brief resolved unexplained event (BRUE) in an infant requires hospital assessment and monitoring. Not a feature Priya has — but must be actively asked about. | 999 — hospital admission; monitoring; respiratory and cardiac assessment |
| Faltering growth ∩ 2 or more centile crossings | Two or more centile crossings in an infant (e.g. 50th to below 9th centile) indicates significant failure to thrive. In the context of CMPA: unmanaged CMPA causes malabsorption; caloric loss from vomiting and diarrhoea; and appetite suppression from pain. Severe growth faltering requires urgent paediatric assessment — not a 2–4 week eHF trial. The GP must also consider other causes: inadequate formula intake; neglect; organic causes (coeliac; metabolic; cardiac). | Same-day or next-day paediatric referral — inpatient admission may be needed for nutritional rehabilitation and investigation |
| Urticaria; angioedema; wheeze; collapse within 2 hours of feed | IgE-mediated anaphylaxis to cow’s milk protein: the most severe form of CMPA. Presents within 2 hours of milk ingestion. Features: urticaria; lip or facial swelling; vomiting (may be very rapid); wheeze/stridor; pallor; collapse. Not Priya’s presentation — but critical to ask specifically (“has she ever had any swelling; hives; difficulty breathing after a feed?”) as this changes management completely (AAF not eHF; EpiPen; urgent allergy referral; no milk rechallenge without allergy specialist). | 999 if acute anaphylaxis. Adrenaline auto-injector (EpiPen Junior 150 mcg) prescribed if anaphylaxis risk. Urgent allergy referral. No milk rechallenge without allergy team. |
| Pale/chalky/acholic stools (white or grey) | Pale acholic stools: biliary atresia — an emergency surgical condition causing progressive obliteration of the bile ducts. Presents in the newborn period with jaundice; dark urine; pale stools. Prognosis depends on early Kasai portoenterostomy (before 60 days of age). Any infant with persistently pale or chalky stools requires same-day urgent referral (biliary atresia excluded) — not a CMPA diagnosis. | Same-day urgent referral — biliary atresia; surgical emergency if confirmed |
Safeguarding and Maternal Wellbeing
💕 Maternal Mental Health
- Edinburgh Postnatal Depression Scale (EPDS): validated 10-item questionnaire; score ≥13 indicates probable PND; score ≥11 with any score on question 10 (self-harm): urgent mental health referral
- Mrs. Sharma: risk factors for PND include sleep deprivation (4–5 hours broken); infant with chronic health problem; stopping breastfeeding (which may generate feelings of failure); anxiety about Priya’s health
- Administer EPDS at this consultation; it takes 2–3 minutes and is a clinical requirement at postnatal reviews
- Health visitor should have completed EPDS at 6–8 weeks review — check if this has happened and what the score was
🏠 Home and Social Situation
- Is Mrs. Sharma’s husband supportive? Is he present at home? Does he do night feeds?
- Is there family support (grandparents; neighbours)?
- Is she isolated? First-time mother in a new area? Social support is protective against PND and infant neglect (which can occur through exhaustion and despair, not malicious intent)
- Any domestic violence concerns? Domestic violence is a risk factor for poor infant outcomes; always ask — NICE-recommended routine enquiry
● Safeguarding — Non-Accidental Injury
- A persistently crying infant is a well-recognised trigger for non-accidental injury (NAI); shaken baby syndrome has its peak incidence at 3–5 months of age — the peak age of infant crying
- The “purple crying” period: normal infant crying peaks at 2–5 months; families need information about safe handling when a baby does not stop crying
- Observe: does Mrs. Sharma handle Priya gently? Any features of concern on examination (bruising; unusual injury patterns; fractures on X-ray if admitted)?
- If safeguarding concern: follow local safeguarding pathway; refer to safeguarding team and social services as appropriate
💕 Breastfeeding Guilt and Identity
- Mrs. Sharma stopped breastfeeding at 2 weeks due to latching difficulties and mastitis — she did not choose to stop from lack of commitment; she was in pain and without adequate support
- The guilt about stopping breastfeeding may be significant and should be directly addressed: “You stopped breastfeeding because you were in pain and it wasn’t working — that was the right decision for you and Priya. Formula feeding is a completely safe and appropriate way to feed a baby.”
- Never imply that breastfeeding would have prevented CMPA (it would not have — breastfed infants get CMPA too; they just need maternal dairy-free diet instead)
😱 Maternal Guilt (Breastfeeding)
Stopping breastfeeding at 2 weeks due to mastitis and latching difficulties is associated with significant maternal guilt, particularly in first-time mothers. This guilt can interfere with the therapeutic relationship if unaddressed. The GP who says “you did the right thing; breastfeeding when you are in pain and struggling is not good for either of you; formula feeding is a completely safe option” removes a significant psychological barrier.
"You stopped breastfeeding because you were in pain and you weren’t getting the support you needed. That was the right decision for you and for Priya at that time. It is not the cause of what is happening now — babies with atopic backgrounds get CMPA whether they are breastfed or not."😴 Sleep Deprivation and Exhaustion
Four months of 4–5 hours broken sleep is a form of significant physical and psychological stress. It is associated with: impaired cognitive function (difficulty processing medical information; remembering instructions); emotional dysregulation; increased PND risk; reduced parenting capacity. Practical support is more important than information at this point: EPDS; health visitor involvement; social support. The formula change plan must be simple enough to implement by someone running on very little sleep.
"I want to ask about you as well. You have not been sleeping. That is really hard. Is there anyone helping you with night feeds? Your husband? Family? I want to make sure you have some support, not just for Priya but for yourself."🖥️ Internet Self-Diagnosis and Anxiety
Mrs. Sharma has been researching for 4 months and may have arrived at CMPA as her own diagnosis. This is often more helpful than harmful — an informed parent who has done research is a parent who is engaged and motivated. The GP’s role is to validate the research, confirm or redirect the diagnosis, and fill in the gaps with clinical reasoning. Never dismiss parental internet research: “You are right — and what you found online is consistent with what I am seeing.”
"You’ve clearly been doing a lot of research. What have you found? I want to understand what you are thinking so we can work through it together."💔 Emotional Cost of a Crying Infant
A persistently crying infant at 3–5 months of age is one of the highest-risk periods for non-accidental injury (shaken baby syndrome). Mrs. Sharma needs to know this is not because the GP suspects her — but because every parent needs information about what to do when a baby will not stop crying (purple crying; safe handling; putting the baby down safely and stepping away). This information is delivered with care and as part of standard parenting support, not as a safeguarding accusation.
"One more thing I want to mention — I ask this with all parents of babies who have been crying a lot: when it gets very hard and Priya won’t stop crying, have you heard of putting her down safely in her cot and stepping away for a few minutes? Sometimes that is the safest thing to do. I know you would never hurt her — but knowing this helps."- Not asking about timing of formula introduction vs symptom onset — the temporal relationship is the cornerstone of the CMPA clinical diagnosis
- Not asking about immediate IgE-mediated features (urticaria; swelling; wheeze — within 2 hours) — missing IgE-mediated CMPA is a significant SCA fail
- Not addressing breastfeeding guilt if Mrs. Sharma mentions it — a missed Relating to Others opportunity that affects the whole consultation

- Simple physiological GOR (happy spitter — good growth; no atopy)Reassurance; thickened feeds or Gaviscon if distressing; 6-month review
- Prescribing Gaviscon again without reassessing — Gaviscon has been tried twice and failed; repeating the same intervention without reassessment is not appropriate management at this stage
- Not weighing Priya and plotting on centile chart — weight trajectory is both a severity marker and a key diagnostic criterion; managing a feeding problem without plotting weight is a significant omission
- Ordering specific IgE or skin prick test for a presentation consistent with non-IgE-mediated CMPA — will return negative; causes false reassurance; inappropriate investigation for this clinical picture
"What I think is happening with Priya is something called cow’s milk protein allergy. The protein in standard formula is from cow’s milk — and Priya’s immune system is reacting to it. It’s not that the formula is bad — it’s that her immune system is treating the cow’s milk protein as if it’s an invader and reacting against it. That reaction causes the inflammation in her gut which is causing the green stools; the vomiting; and the discomfort. It also explains the skin rash on her cheeks. This is quite common in babies — about 2 in 100 have it — and the great news is that most children grow out of it completely by the time they are three to five years old."
"The health visitor said it was reflux — was she wrong?"
"The health visitor wasn’t wrong to start there — what Priya has does look like reflux, and Gaviscon was a completely appropriate first step. But Gaviscon treats the reflux mechanically, by thickening the stomach contents. If the underlying problem is an allergy — which I now think it is — Gaviscon can’t help with that part. That’s why it has not been working. What we need now is a formula that doesn’t contain the protein that Priya is reacting to."
"Did stopping breastfeeding cause this?"
"No. Breastfed babies can get cow’s milk protein allergy too — it just comes through the mother’s milk if the mother is eating dairy. Stopping breastfeeding did not cause this. What matters now is what we do from here — and that is something we can fix."
Good weight gain; no atopy; not distressed
70% of infants at 4 months; peaks at 4 months; resolves by 12–18 months. No eczema; no family atopy; weight tracking well; normal stools. Management: parental reassurance; positioning; thickened feeds or Gaviscon if concerning parents.
Immediate reactions (<2h); anaphylaxis; or 2× centile drop
IgE-mediated: urgent allergy referral; SPT or specific IgE; EpiPen; AAF (not eHF until tested). GORD with 2× centile drop: urgent paediatric referral; PPI may be appropriate; endoscopy if severe.
- Blaming the health visitor or implying that previous management was wrong — Gaviscon was appropriate as a first step; the clinical picture has evolved; undermining the health visitor damages the parent’s relationship with other healthcare professionals
- Not referring to a paediatric dietitian for a child with CMPA and faltering growth — dietitian is essential for milk ladder guidance and weaning planning; this is not optional in a child who has dropped a centile
Validate what has already been tried
Gaviscon was not a wrong treatment — it was the right first step for what looked like reflux. The clinical picture has evolved. The GP who validates previous management — including the health visitor’s advice — maintains Mrs. Sharma’s trust in the healthcare system and avoids undermining the health visitor.
"The Gaviscon was exactly the right thing to try first. It was a completely appropriate step — it just treats the reflux mechanically, and if the underlying problem is an allergy, it can’t fix that part. Now we know more, we can target what is actually causing the problem."Explain why this is different from what has been tried
Mrs. Sharma needs to understand why this formula change is different from any previous attempt — otherwise she may not implement it, or may mix eHF with standard formula, or may not persist for the full 2–4 weeks. The key concept: the new formula has been broken down to the point where Priya’s immune system does not recognise it.
"The formula I am going to prescribe — it is called an extensively hydrolysed formula — has the cow’s milk protein broken down into tiny fragments that Priya’s immune system will not react to. It is not a standard formula and it is not a comfort formula — it is a medical formula prescribed specifically for this problem."Give a clear timeline and a specific review
Mrs. Sharma has been managing uncertainty for 4 months. A specific timeline and a booked review appointment provide the predictability and hope that she needs. The 2–4 week timeline is achievable; the review appointment makes the plan concrete.
"Most babies start to improve within 1–2 weeks of the formula change. By the end of 4 weeks, if Priya has improved, we will know that cow’s milk was the problem. I want to see you both back in 2 weeks — I am going to book that appointment now so it is in the diary."The eHF must completely replace standard formula from day 1 of the trial. Any residual standard formula in the feeding regimen (e.g. mixing one bottle per day; using SMA First for night feeds because eHF is more expensive) will prevent symptom resolution and invalidate the trial. Mrs. Sharma must be told: complete replacement from today. If she cannot afford the eHF formula: it should be prescribed on FP10 (GP prescription) — NHS prescription for approved CMPA management. All eHF formulas are prescribable in primary care.
Prescribed eHF: Nutramigen 1 with LGG; Aptamil Pepti 1; SMA Althera (birth to 6 months). 150–200 ml/kg/day as with standard formula. The formula may smell different (characteristic hydrolysed smell); this is normal and does not indicate it is spoiled. Some infants initially refuse eHF — introduce gradually over 1–2 days if needed (e.g. start with 80% eHF: 20% standard; increase to 100% over 2–3 days). Check formula preparation technique (one level scoop per 30 ml water; correctly made up).
Positioning after feeds reduces GOR by reducing the time oesophageal contents are in contact with the oesophagus in the lying position. Evidence for upright positioning is modest but widely recommended. Smaller more frequent feeds reduce the volume of gastric contents at any one time. Relevant for Priya even after eHF switch — reflux may take a few weeks to resolve completely even after formula change because gut inflammation takes time to heal.
After feeds: upright (held against shoulder; bouncy chair at 30-degree incline) for 20–30 minutes. Winding mid-feed and after feed. Smaller volumes more frequently if vomiting large amounts after feeds. Sleep position: back to sleep (supine) — always; never prone sleeping. Car seat should not be used for prolonged post-feed positioning.
Priya’s eczema is both a marker of CMPA (atopic inflammation driven by milk allergy) and a separate problem requiring treatment. Emollient therapy: Diprobase; Epaderm; Hydromol — applied liberally twice daily to all skin (not just affected areas); emollient repairs the skin barrier disrupted by atopic inflammation. Topical hydrocortisone 1% (face-safe; weakest topical corticosteroid): applied to active eczema areas for 5–7 days; then stop. Eczema will typically improve with eHF formula change as the underlying CMPA inflammation resolves — but acute eczema should be treated alongside.
Emollient: Diprobase cream; apply after bath and before feeds; use a spoon or spatula (not fingers directly into pot) to reduce contamination. Topical HC 1%: apply twice daily to red/inflamed areas; avoid eyes; avoid normal skin. NICE: step up to 2.5% HC if 1% fails; moderate-severe eczema: referral to paediatric dermatology.
All infants in the UK are recommended vitamin D supplementation: 8.5–10 mcg (340–400 IU) daily from birth to 1 year (Healthy Start vitamin drops; or infant vitamin D drops). Formula-fed infants receiving >500 ml standard or eHF formula per day: formula is fortified with vitamin D and supplementation is not routinely needed. If taking <500 ml/day formula (possible with a vomiting infant): supplement. Breastfed infants: must supplement as breast milk is low in vitamin D. Check that Priya is receiving adequate vitamin D given her current reduced intake from vomiting.
Healthy Start vitamins (free for qualifying families). Alternatively: Abidec drops (contain vitamin D); Bio-D-mulsion drops. Check whether Mrs. Sharma is registered for Healthy Start scheme (entitled if in receipt of certain benefits or if pregnant/has a child under 4).
A simple feeding diary maintained by Mrs. Sharma allows the GP to objectively assess response to eHF at the 2-week review. Without a diary: it is difficult to distinguish “she seems better” from “she is definitely better”. The diary also helps Mrs. Sharma feel in control (she is actively participating in the investigation) and reduces anxiety by giving her something constructive to do. Format: simple chart with date; feeds (volume; time); stools (colour; consistency); symptoms (crying episodes; vomiting; eczema); weight when available.
Provide a template or direct to an app (NHS Start4Life; CMPA Support websites). At the 2-week review: review the diary together. Improvement in symptoms — particularly stool normalisation and reduction in crying — confirms eHF is working.
If Priya were breastfed: the management would be maternal dairy-free diet for 2–4 weeks — NOT formula change. The infant continues breastfeeding. Mother must avoid: all dairy (milk; cheese; yoghurt; butter; cream; any product with milk on the ingredient list). Calcium supplementation for the mother: 1000 mg/day (dairy is the primary dietary calcium source; must be replaced). Vitamin D: 10 mcg/day. Soy milk acceptable for the mother (but soy formula is NOT appropriate for the infant under 6 months). Most mothers find the dairy-free diet challenging — dietitian support is essential.
Not applicable for Priya. Explanation: “Because Priya is on formula, we change the formula. If you were still breastfeeding, I would ask you to cut out dairy from your own diet instead — but the principle is the same.” This explanation also addresses any lingering guilt about stopping breastfeeding — the management would have been different, but not necessarily easier.
- Nutramigen 1 with LGG; Aptamil Pepti 1; SMA Althera (birth to 6 months)
- Complete replacement of standard formula from day 1; no mixing
- Prescribable on FP10 (NHS prescription) — prescribe as a named product not generic
- 150–200 ml/kg/day; same volume as standard formula
- Neocate Infant; Alfamino; Nutramigen AA (amino acid formula)
- For: IgE-mediated CMPA pending allergy testing; eHF failure after 4 weeks; severe non-IgE-mediated with multiple food allergies
- NOT for routine non-IgE-mediated CMPA as first-line — eHF is less expensive and sufficient
- Prescribable on FP10; typically initiated after allergy team review
- HA formula (SMA HA; Aptamil Comfort): partially hydrolysed; NOT sufficient for CMPA diagnosis or treatment; protein still antigenic enough to cause reactions
- Goat’s milk formula: major cross-reactivity with cow’s milk (~90%); NOT safe for CMPA
- Soy formula under 6 months: phytoestrogens; not recommended for infants under 6 months; 10–14% cross-react with soy anyway
- Omeprazole: NOT for simple GOR or CMPA; only for confirmed GORD with complications
Select infant characteristics — CMPA and reflux management guidance
"The formula I am prescribing today is called an extensively hydrolysed formula. It is different from standard formula because the protein has been broken down into tiny pieces that Priya’s immune system won’t recognise. It is a medical formula — and it goes on prescription, so there is no cost to you. It smells a bit different from what you have been using — that is completely normal. Some babies take a couple of days to get used to the taste. Replace all of Priya’s feeds with this from today."
eHF: first-line formula for non-IgE-mediated CMPA (the iMAP guideline; MAP guidelines). Prescribable on FP10. NOT HA formula (most common SCA error) — HA is partially hydrolysed and NOT appropriate for CMPA. NOT goat’s milk (major cross-reactivity). NOT soy under 6 months. Full switch from day 1; 150–200 ml/kg/day; review at 2–4 weeks. Improvement expected in 1–2 weeks. If no improvement after 4 weeks: AAF; allergy team.
"This formula contains only the most basic building blocks of protein — called amino acids — rather than any protein that your baby’s immune system could react to. It is a complete food source and provides everything your baby needs. It does have a different taste, and some babies take a few days to get used to it. Like all of the special formulas, this is on prescription."
AAF: for IgE-mediated CMPA (pending allergy testing); eHF failure after 4 weeks; multiple food allergy. NOT first-line for straightforward non-IgE-mediated CMPA. Products: Neocate Infant; Alfamino; Nutramigen AA. All prescribable on FP10. Allergy team should confirm continued use and weaning plan. Milk ladder for IgE-mediated CMPA must be supervised by allergy team (anaphylaxis risk).
"I would like to continue the Gaviscon alongside the new formula for now — it helps with the reflux while the new formula is getting to work on the underlying allergy. Once Priya is better on the new formula, we can decide at the next appointment whether she still needs the Gaviscon. Just remember: do not use the Gaviscon with a thickened formula — that can cause constipation."
Infant Gaviscon: alginate-based; for GOR and ongoing reflux alongside eHF. NOT a treatment for CMPA itself. Third course of Gaviscon without formula change = Tasks fail in SCA. Formula-fed: 1 sachet per feed. Breastfed: half sachet in 15 ml cooled water by syringe. NOT with thickened feeds. NOT in preterm. Constipation: reduce dose. Discontinue at review if eHF has resolved symptoms.
"This tablet helps reduce the acid in your baby’s stomach, which should make the reflux less painful. I want to be clear: we are using it because we have evidence that the acid is causing a real problem — not just as a trial. I want to review Priya in 4 weeks to make sure it is making a difference."
Omeprazole in infants: ONLY for confirmed GORD with complications (faltering growth; oesophagitis; aspiration). NOT for simple GOR. NOT as diagnostic trial. NOT for CMPA (wrong mechanism). Unlicensed under 1 year — document rationale. Dose: 0.7–1.4 mg/kg/day; max 20mg. Review at 4–8 weeks. Evidence: multiple RCTs show NO benefit over placebo for crying infants without GORD. Prescribing omeprazole for Priya without first changing formula = Tasks fail in SCA.
"Because of the reaction Priya had — with the hives and the swelling — I want to make sure you have this pen at all times. If you see those signs again — hives; swelling; difficulty breathing — you use the pen in the outer thigh and call 999 immediately. The nurse from the allergy clinic will train you on how to use it and give you a written plan. You should always carry two."
EpiPen: ONLY for IgE-mediated CMPA with anaphylaxis history or risk (confirmed by allergy team). NOT for non-IgE-mediated CMPA (Priya). EpiPen Junior 150 mcg for <15 kg. 2 devices prescribed. Written allergy action plan essential. Train parents and nursery staff. 999 after administration. Annual review. Do not prescribe EpiPen for CMPA without allergy team involvement.
"I am also going to prescribe a moisturising cream for Priya’s skin — you should use it generously twice a day, every day, not just when she has a rash. Think of it as feeding her skin. And I am going to prescribe a mild steroid cream for the red patches — use it on the rash twice a day for a week when it flares up; then stop when it clears. The formula change should also start to help her skin — most babies see real improvement in the eczema within 2–4 weeks."
Emollient + HC 1%: prescribe at first appointment alongside eHF for all CMPA with eczema. Emollient twice daily (Diprobase; Epaderm); HC 1% twice daily to active areas for 5–7 days. Face-safe. Eczema will improve as CMPA resolves on eHF over 2–4 weeks — but treat the acute inflammation now. SCORAD at baseline and review. Step up to HC 2.5% or betamethasone 0.025% if inadequate response. Paediatric dermatology if severe. Topical calcineurin inhibitors (tacrolimus): from 2 years only.
Maternal Guilt
Mrs. Sharma is carrying guilt about stopping breastfeeding. CMPA occurs in breastfed infants too — the management would simply have been maternal dairy-free diet. Stopping breastfeeding did not cause CMPA and would not have prevented it. The GP must address this directly without minimising: “stopping breastfeeding when you were in pain was the right decision.”
"Can I say something about the breastfeeding? Stopping when you did was the right thing to do — you were in pain, and continuing was not sustainable. Cow’s milk allergy happens in breastfed babies too. This is not something you caused."Parental Exhaustion
Four months of broken sleep is a medical concern. Parental exhaustion increases the risk of PND; reduces ability to implement feeding changes accurately; increases risk of errors in formula preparation; and reduces capacity to respond appropriately to infant cues. EPDS is essential. Practical support (partner involvement; family help; health visitor home visits) is clinically as important as the prescription.
"I also want to check in about you. How are you coping with the sleep? Is there anyone helping you? I want to make sure you have some support too — not just for Priya’s sake but for yours."Weaning and Social Feeding
CMPA affects weaning planning: dairy-containing solids cannot be introduced at 6 months without the milk ladder; this requires dietitian input and careful planning. Social feeding (attending baby groups with snacks; birthday parties; nursery) becomes more complex. Parents need information about hidden dairy in food labels and how to communicate the allergy to childcare providers.
"When Priya starts on solid food at around 6 months, the dietitian will help you work out how to introduce things gradually — there is a specific order and timeline that means most babies can have normal dairy food by the time they start school."Prognosis and Hope
The single most important message to give Mrs. Sharma alongside the diagnosis is the prognosis: 90% of children with non-IgE-mediated CMPA develop complete tolerance by age 5. Most children are tolerating baked milk products by 12–18 months. This is not a lifelong condition. The GP who gives this clear, specific, hopeful message provides something Mrs. Sharma can hold onto during the difficult weeks of the eHF transition.
"The really good news — and this is important — is that 9 out of 10 children with this type of allergy grow out of it completely by the time they are 5. Most children are eating normal dairy food — cheese; yoghurt; everything — by school age. This is not going to last forever."Today — eHF prescribed; EPDS; eczema management; referrals
eHF (Nutramigen 1 with LGG or Aptamil Pepti 1) prescribed on FP10; explained to Mrs. Sharma; complete switch from today. Infant Gaviscon continued alongside. Emollient (Diprobase) + topical HC 1% prescribed for eczema. EPDS administered; result documented. Health visitor alerted. Dietitian referral made. Allergy team referral. 2-week review booked before leaving.
2 Weeks — Weight recheck; symptom diary review; eHF response
Weight (plot on centile); feeding diary review (stool normalisation; reduction in crying/vomiting; eczema improvement); eHF adherence confirmed (complete switch; no standard formula). If improving: confirm CMPA diagnosis; continue eHF; book 4-week review. If not improving: review adherence; consider formula preparation; check for any dairy in diet; consider AAF if fully adherent and no improvement. EPDS recheck if previous score was elevated.
4–6 Months — Allergy team review; milk ladder planning
Allergy team review (if referred). Weaning planning: dietitian advises on milk ladder starting from 6 months. Milk ladder step 1: baked milk products (biscuits, cakes). Weight; centile; developmental check. SCORAD eczema review. If well-controlled on eHF: trial of milk ladder (baked milk) supervised by dietitian/allergy team. If any IgE features emerge: SPT or specific IgE before milk ladder.
12 Months — Milk ladder progression review
Review milk ladder progress (most non-IgE-mediated CMPA tolerates baked milk by 12–18 months). If milk ladder progressing well: continue through steps under dietitian guidance. Annual allergy review. Eczema management review: does eczema improve as CMPA resolves? Any other allergies emerging at weaning (egg; peanut — now recommend early introduction at 4–6 months as allergy prevention in atopic infants: LEAP trial).
Age 3–5 — CMPA resolution expected
90% of non-IgE-mediated CMPA resolves by age 5. Full review at 3 and 5 years with allergy team: has Priya developed complete tolerance? Formal rechallenge if not spontaneously tolerating. If tolerance confirmed: discharge from CMPA monitoring; normal dairy diet. If persisting: review whether IgE-mediated component (repeat SPT/specific IgE); ongoing specialist follow-up; school alert and management plan.
CMPA monitoring mnemonic: WASTE
Weight: centile plot at every review. Allergy features: new IgE-mediated features; new food allergies at weaning. Stools: normalisation from green/watery to normal formula stool (yellow; seedy) within 2–4 weeks confirms eHF response. Twenty-four hours: symptom diary; feeding diary reviewed at each appointment. Eczema: SCORAD at each review; improvement confirms CMPA diagnosis.

Who you are
Anita Sharma, 28, first-time mother. Baby Priya is 4 months old. Priya was born at term and breastfed for 2 weeks, but Anita developed mastitis and latching difficulties so switched to SMA First. Anita feels guilty about stopping breastfeeding and is worried it has caused Priya’s problems. She has been sleeping about 4–5 hours of broken sleep per night since Priya was born. Her husband works long hours. She has been researching online and wonders if Priya has cow’s milk protein allergy — she wants someone to confirm or deny this.
Hidden agenda — disclose if GP creates space
Breastfeeding guilt (disclose if GP addresses it, or if GP says CMPA is not her fault): “I stopped breastfeeding at 2 weeks because I had mastitis and it was agony. But then when Priya started getting worse, I kept thinking — did I do this? Did switching to formula cause this?” Respond well if GP says: "Stopping when you were in pain was the right decision — breastfed babies get this allergy too." Then visibly relieved: “Really? I’ve been blaming myself for months.”
CMPA self-diagnosis (share if GP asks about ideas): “I looked it up online — a lot of what they describe sounds exactly like Priya. Cow’s milk protein allergy. Is that what this is?” Respond well if GP validates: “Oh, good — I was worried you’d think I’d been on Dr Google too much.”
Health visitor relationship (raise if GP asks about ICE or previous management): “I don’t want to get the health visitor in trouble — she was really helpful. I just feel like the Gaviscon hasn’t done anything and I needed to see someone else.” Respond well if GP validates the health visitor’s initial management: “OK. That makes sense.”
Responses to key conversations
- On CMPA diagnosis: "So it is an allergy? Not just reflux?" — respond to clear explanation: "OK. So the Gaviscon was never going to fix it because it was the wrong problem? That actually makes sense."
- On eHF formula: initially: "Will it actually work? We have already tried changing things and nothing has helped." — respond to explanation of mechanism and evidence: "OK. And it’s on prescription? I didn’t know you could get formula on prescription."
- On no blood test: initially puzzled: "Don’t you need to test to know for sure?" — respond to explanation: "Oh — so the formula change is the test. That’s interesting. OK."
- On prognosis: visibly relieved: "90% grow out of it? I thought this might be forever." — this is the emotional turning point of the consultation; the actor should show visible emotional shift here.
- On eczema cream: "I hadn’t thought of the rash as being part of the same problem. That makes sense actually."
Clinical details
- Baby Priya: 4 months; term birth; 3.8 kg at birth (50th centile); now 4.2 kg (25th centile)
- Formula: SMA First since 2 weeks; Infant Gaviscon ×2 (no benefit)
- Symptoms since 3 weeks: crying after feeds; back-arching; vomiting 1–2 times per feed; green watery stools
- Eczema: both cheeks (mild to moderate)
- Family atopy: father asthma; mother hayfever
- No bilious vomiting; no blood in stool; no apnoea; no fever
- Mrs. Sharma: EPDS (administer in consultation) — likely score 9–11 (sleep deprivation; infant illness; guilt; anxiety); borderline PND; close follow-up needed
Resolution: Mrs. Sharma accepts the CMPA diagnosis and eHF prescription if: the health visitor is not criticised; the breastfeeding guilt is addressed directly; the formula change is explained clearly in plain language; and a 2-week review is booked before she leaves. She is visibly relieved when the prognosis is given (90% resolve by 5). She leaves saying: “I feel like I finally have an actual answer. I’ve been going round in circles for months.”
