Cow’s Milk Allergy is a spectrum condition, affecting 1 in 20 infants in their first year of life. It presents with a wide range of symptoms, sometimes difficult to distinguish from other common issues in infancy such as colic, regurgitation or loose stools. Both immediate and delayed reactions to cow’s milk are more common in atopic families; those with asthma, eczema or hayfever, eczema being particularly associated with CMA in infancy. Delayed reactions typically show up in the gastrointestinal tract and skin.
Cow’s Milk Difficulties presenting with lower abdominal symptoms eg. loose, smelly, bloody or mucus pooh, constipation or painful wind and upper abdominal symptoms such as vomiting, reflux, pain after feeding and feeding aversion will impact an infants’ enjoyment and willingness to feed well. For delayed reactions to cow’s milk, at least two persistent symptoms are needed to consider a diagnosis alongside an allergy focussed history.
