Case Study: Specialist Dietetic Support for Cow’s Milk Protein Allergy in Primary Care

A baby experiencing symptoms of cows’ milk protein allergy (CMPA), such as irritability, crying, and discomfort.

Overview

Cow’s milk protein allergy (CMPA) is one of the most common childhood food allergies, but diagnosis and management can be challenging for both families and healthcare teams.

Within one of our Primary Care Network (PCN) clinics, a GP referred a 7-month-old infant presenting with ongoing reflux, loose stools, and poor weight gain despite feeding adjustments.

Our dietitian worked closely with the family to provide clear guidance, ensure nutritional adequacy, and support the transition to a suitable milk alternative and safe weaning foods.

Our Impact – Case Outcome

  • Symptoms improved within 2 weeks of eliminating milk safely
  • Infant’s weight gain returned to the 50th centile within 3 months
  • Parents reported increased confidence in managing the allergy and preparing balanced meals
  • There were fewer follow-up visits for feeding concerns, freeing up clinical time
  • Family provided with a clear reintroduction plan to assess tolerance at the appropriate age

What Made This Case Successful

Our dietitian’s approach combined clinical expertise with practical, family-friendly advice:

  • Tailored feeding plan - Advising on dairy-free weaning options
  • Nutrient optimisation - Ensuring calcium, vitamin D, and protein needs were met without dairy
  • Practical resources - Providing recipe ideas, shopping lists, and label-reading guidance
  • Parental reassurance - Addressing concerns about growth, nutrition, and allergy safety

Clinic Process for CMPA Management

  1. Initial assessment - Reviewing feeding history, symptoms, growth data, and family concerns
  2. Education - Explaining CMPA, safe/unsafe foods
  3. Dietary adjustments - Implementing a an elimination diet while maintaining balanced nutrition
  4. Monitoring - Tracking symptom changes and growth over time
  5. Reintroduction planning - Guiding parents on safe reintroduction/milk ladder when appropriate

Parent Feedback

“We finally understand what’s been upsetting our baby. The dietitian explained everything so clearly and gave us a plan we could follow.”

“Having recipes and shopping tips made such a difference – I felt less stressed and more confident.”

Looking Ahead

This case highlights the value of having dietitians embedded in PCN clinics to support early diagnosis and management of food allergies.

By providing families with specialist advice early, we can:

  • Improve growth and symptom outcomes for children with CMPA
  • Reduce unnecessary GP visits and hospital referrals
  • Give parents the confidence and skills to manage their child’s diet safely

We aim to expand allergy-focused dietetic clinics within PCNs and provide training to health visitors and GPs on recognising and managing CMPA in primary care.
