We believe breast milk is the best food for infants. When in consultation with their healthcare professional, mothers and families find that optimal breastfeeding is not possible due to their infant’s medical condition, formulas for special medical purposes play a vital role in providing essential nutrients to infants. We have a global commitment to market breast-milk substitutes responsibly.

Cows’ Milk Allergy

Could it be cows’ milk protein allergy?

Do you suspect that your baby may be allergic to proteins in cows' milk?

Cows' milk protein allergy (CMPA), also known as cows' milk allergy (CMA), is one of the most common food allergies in babies and young children. The symptoms can be distressing, but CMA can be easily managed with the correct diet, so getting a diagnosis is very important. The good news is that the vast majority of children who are allergic to cows' milk will outgrow this by the time they are 3 years old.

Can CMA affect your baby’s feeding?
Once diagnosed, cows’ milk allergy symptoms can be easily managed with the correct support.

Your doctor or health care professional (HCP) will advise you on how to improve your baby’s symptoms and eliminate cows’ milk protein from your baby’s diet. This should in no way affect your breastfeeding routine.

Breastfeeding is the best way of feeding your baby during the first months of life and is preferred whenever possible. It is also the preferred choice of feeding for a baby with CMA.

If you choose to move on from breastfeeding, your doctor or HCP will help you identify suitable alternatives. They can also support on the avoidance of cows’ milk protein during complementary feeding (weaning).

Breastfeeding and CMPA



What is CMA?


CMA is a food allergy where your baby’s immune system reacts abnormally to proteins in cows’ milk. In rare cases, even babies who are exclusively breastfed may develop CMA by reacting to the cows’ milk protein that is transferred through the breast milk.


About CMA

Recognise signs and symptoms of CMA

Symptoms of CMA can affect the digestive system (e.g. diarrhoea or vomiting), the respiratory system (e.g. runny nose or cough) and the skin (e.g. dry and scaly skin).

How to obtain a diagnosis of CMA

Diagnosing CMA can be challenging. If CMA is suspected, you should visit a doctor who can assess and if necessary perform specific tests to help make a diagnosis. Keeping a symptom diary may support this.

IMPORTANT NOTICE: Breastfeeding is the best form of nutrition for babies and provides many benefits to babies and mothers. It is important that, in preparation for and during breastfeeding, you eat a healthy, balanced diet. Combined breast and bottle feeding in the first weeks of life may reduce the supply of your own breastmilk, and reversing the decision not to breastfeed is difficult. Always consult your healthcare professional for advice about feeding your baby. The social and financial implications of using infant formula should be considered. Improper use of an infant formula or inappropriate foods or feeding methods may present a health hazard. If you use infant formula, you should follow the manufacturer’s instructions for use carefully – failure to follow the instructions may make your baby ill. Formula for special medical purposes intended for infants must be used under medical supervision.
