<<Disclaimer: Verify this information before applying it to your situation.>> I have Celiac. I have kept my 18 mo old son on a gluten-free diet with the exception of an occasional snack of Cheerios which do not seem to affect him. One day he ate a few cheese nips. The next day he had a huge, loose bowel movement. Then, the other day, he ate about a handful of goldfish crackers that a playmate had. The next day his stool was very watery and yellow. Do you think this is a sign of Celiac, or could this just be a reaction to having wheat for the first time? Needless to say, I am very upset and awaiting your response.Thanks for your help.
