Cow's milk allergy is the most common food allergy among infants and it affects at least one in 50 babies, toddlers and pre-school children in the UK. It's an allergic reaction to the protein in cow's milk. There are two different types though and one type, called delayed cow's milk allergy, is often missed by health care professionals because it's easily confused with other common conditions. Lucy Wronka tells Inside Health her baby son George was ill for months with reflux, eczema and an upset stomach. It was only a chance meeting with a friend who recognised the symptoms that led to a diagnosis of delayed cow's milk allergy. Twenty four hours after diagnosis and treatment, Lucy says George was a different baby. Dr Adam Fox, paediatric allergist at the Evelina London Children's Hospital explains the difference between the two different types of cow's milk allergy and discusses new guidance for GPs and health visitors which are designed to improve diagnosis.
