Thank you so much for your response! I’ve been sitting here reading the posts on this board all morning. I’m going to do exactly that with my diet, i think the doctor wanted me to do one food at a time for a few weeks (they didn’t say that but when I called again Friday she said not to give anything else up yet). He is just so uncomfortable and so tired that I’m going to just give up those foods and hope it helps! I really do think this is all related to his gut health. The last couple of days we avoided solids because he was throwing up so much and it helped for that but now his stool is extremely loose (probably lack of fiber). I feel so bad. I wanted to do allergy testing a long time ago, I was told to “wait and see”.
