Milk Allergy

Cows' Milk Allergy (CMA) happens when a child's immune system reacts to proteins in milk thinking they may be harmful. This can cause celayed symptoms which develop slowly over several days or, more rarely, an immediate reaction.

• CMA affects only 2-3% of babies but most will outgrow the allergy and can get back to eating and drinking dairy between 1 and 2 years of age

• CMA is more common in babies where there is a history of eczema, asthma, hayfever or food allergy in close family members, but can happen when these are not present

• CMA can affect babies who are exclusively breastfed although this is unusual. More commonly it affects babies being formula fed, or having a combination of formula and breastmilk. Or it can happen when a breastfed baby has foods which contain cows’ milk introduced to their diet.

If you think your baby is having a reaction to cows' milk, see your GP to discuss your concerns.
