My Baby Has CMPA — What Happens Next?
Hearing that your baby may have cow’s milk protein allergy (CMPA) can bring relief, worry and a long list of new questions at the same time. You do not need to master everything in one day. The next steps are easier when you take them in order.
1. Clarify how the diagnosis is being made
Your healthcare professional should begin with an allergy-focused clinical history. The next step depends on whether an immediate IgE-mediated allergy or a delayed non-IgE-mediated allergy is suspected.
2. Follow the agreed elimination and reintroduction plan
For suspected delayed food allergy, NICE guidance recommends a trial elimination of the suspected allergen followed by planned reintroduction, with appropriate dietetic advice. Do not extend or broaden dietary restriction without a clear reason.
3. Protect feeding and nutrition
Breastfeeding can usually continue. If formula is required, use the hypoallergenic formula or milk substitute recommended for your baby. Ordinary plant drinks are not a substitute for infant formula unless a qualified healthcare professional has specifically advised otherwise.
4. Learn the basics of label checking
Milk must be emphasised when present as an ingredient in UK prepacked food. Check every current label rather than relying on a product having been suitable before.
5. Build a small set of reliable foods and meals
You do not need dozens of specialist products immediately. Start with familiar naturally dairy-free foods and a few suitable replacements, then build from there.
6. Approach weaning normally, with suitable adaptations
When your baby is ready for solids, continue age-appropriate weaning while excluding the allergen you have been advised to avoid. Ask for personalised advice on formula, milk alternatives and other allergens where needed.
7. Do not automatically remove soya
Some children with CMPA may also react to soya, but this is not automatic. Additional restriction should be based on the individual child and professional advice.
8. Remember that CMPA is a journey
Over time, your priorities will move from understanding symptoms and diagnosis to feeding, labels, weaning, family meals and eventually discussions about reintroduction or tolerance where appropriate for your child.
