Thanks. His problem behaviors only occur at home, though. Is it possible for him to compensate for these things in other environments? It seems if it were a food sensitivity, he'd have behavior issues across the board.
I agree; it seems unlikely to me that these behaviors could be rooted in food intolerance.
And I wouldn't go for dietary changes on my own; if you have reason to think there are gut issues (constipation, frequent diarrhea, reflux being some observable signs) you should talk to a doctor. Mum3's recommendations are very sound.
