M.S.
I am not sure what other moms have said. I don't know much about allergies but I know A LOT about pediatricians. The one thing that I really want to stress to you is that if YOU are worried, you have the right to tell your pediatrician that YOU want your baby tested. It is not the pediatricians right to tell you not to worry that he is right. I have heard that before and they are NOT ALWAYS RIGHT. If he won't test, tell him that is was sure a pleasure having him as a doctor but that you will be taking your son somewhere else from now on. YOU are the MOM and YOU have the instinct to follow. Don't be afraid to follow that mommy instinct. It is usually right and any doctor worth their beans will tell you the same. Hope this helps and gives you some courage!
Good Luck
