What is Cow’s Milk Allergy? A simple enough question, and one you would think most doctors would be able to answer. Why then, in this day and age do we find that GPs struggle to diagnose this illness? I may be over reacting here, but it is my experience. I want to take this opportunity to share it with you because no parent should have to live through the nightmare. Hopefully this might go someway to raising the awareness of this illness.
