S.D.
I went through this too! My daughter was allergic to everything!!! I was down to eating rice, chicken and a couple of veggies. I lost a bunch of weight. But, whatever she needs I'm going to do! He should be old enough to do allergy testing since you are having big problems. One Dr. told me 6 months was too young. Then another said 6 months is old enough. Have you tried cuuting out all dairy? It is very difficult. I tried it for 2 weeks, nothing. Decided to try again for 3 weeks of no dairy, success! It took that long to get out of my system. She did better after that and all of the other things I cut out. She still deals with the food allergies and it can be very hard at times b/c most people have no clue about them. But, I would definately take him to a pediatric allergist!!! Also, there is a support group called boulderallergykids.com. Good luck and take care!
