M.N.
I agree w/ the other responses in that 1) pediatricians won't usually test for allergies until the child is much older and 2) the pediatrician should at least explain his/her reasoning and if not, then switch peditricians ( Plano Pediatrics is a good choice ). I have bad allergies and my daughter started having symptons when she was about 6 months old. Dr. Katz ( at Plano Pediatrics ) told me that he couldn't test at such a young age, but since I had allergies, it was highly likely that she did as well. At about 1, he put her on zyrtec and rhinocort and she's been on it ever since and her symptoms and the amount of sinus infections has drastically been reduced. I have not had her officially tested yet, but I know that if I stop the medication, she gets a sinus infection. At 3 months, it is very possible that the child could just be having reactions to formula, milk, and/or something the mom has been eating if she breastfeeds. At any rate, i would switch to a more open and compasssionate doctor.
