Please have your child tested for Celiac Desease. This is an allergy to Gluten, as in wheat, barley, oatmeal etc. It took over 15 years before my husband was finally diagnosed. There is no treatment for this. A lifelong glutenfree diet is the only way, but it is really not that bad because a lot of the supermarkets and of course the healthfood stores have glutenfree pasta, bread cookies etc . In Europe every Newborn is automatically tested for this allergy, Hopefully it will happen in this country soon. Please insist that your doctor performs this test. If he refuses, go to a Gastroenterologist and have it done. Good luck.
