WE will see his pediatrician on tiesday and I will talk to her... she was very understanding as an infant he was not tolerant of most formula(or breast milk) but i never thought it might be gluten that was bothering his tummy. Yesterday my MIL gave him a ritz cracker and her was awake a good portion of the night ( not really crying just complaining) my husband still doesn't think its a link to gluten. He is not small and is chunky too so he says see he is ok. But i am trusting my instincts on this. My daughter has had headaches and slpit second vision blackouts for almost a year with no diagnoses or answers just test all come back normal I will ask about her too.
