Jessica, as I wrote to Naomi below, Tom does not have celiac but I do (diagnosed 4 years ago). First of all, if you suspect celiac, you should not put Joey on a gluten free diet. He needs to be eating gluten for any tests to be valid! Second, has your ped done a blood test to screen for celiac? This is something that can be done right away before seeing the GI.
Celiac is tricky to diagnose just on symptoms... but the blood test is the best first step. You want to be sure because living gluten free is not something you want to do for life based on a suspicion. It's managable and livable.. but I wouldn't do it if I didn't absolutely have to!
