Is Corn the Culprit?

Now, under the advice of a mom who has done research with PDD-NOS kids and their diets, I am trying a corn-free diet rather than the gluten-free/casein-free diet. Well, actually, Alec has been off of dairy for some time and I plan to continue that. But I think I will START with the corn. I have seen that after eating popcorn he is especially foggy and has incoherent babble. He pretty much has been eating corn constantly in lieu of the wheat. Hmmmm.

Alec starts school tomorrow. Excited and apprehensive for him. I am hoping for the best for my little guy!
