Cow's milk protein allergy in babies: how to choose and change formula
Changing formula is part of treatment. It should be done under a doctor's guidance, not by frequent trial and error.
Why you should not change formula casually
Standard formula, partially hydrolysed formula, extensively hydrolysed formula and amino acid formula are for different situations. For babies with a confirmed cow's milk allergy, standard formula and partially hydrolysed formula are usually not suitable. A doctor needs to choose the right product based on how severe the symptoms are, the baby's age and their nutritional status. Frequently switching between different formulas makes it hard to judge symptoms and may delay treatment.
Points to note when changing formula
- Let the doctor decide the type of formula and how long to use it. Do not increase, reduce or mix formulas on your own.
- After the change, record any changes in symptoms: rash, vomiting, diarrhoea, weight and how well the baby feeds.
- Special formulas taste and smell different. A baby may need time to get used to them.
- Soy formula and goat's milk formula are not suitable for all babies with allergies. Follow the doctor's advice.
- Go to follow-up visits as planned. The doctor will decide when the allergy can be reassessed.
The two things parents should focus on most
First, nutrition and growth: measure weight and length regularly to make sure the baby gets enough energy and nutrients while avoiding the allergen. Second, safety: make sure the family has a clear plan for emergencies. If the baby has had a severe reaction, keep the emergency plan prescribed by the doctor ready and make sure all carers know about it.
