We haven't had any adverse withdraws and we haven't had a problem finding things for him to eat. He hasn't asked for anything with gluten, and I think that he's adjusting.
I've really enjoyed trying the different gluten free foods, and I even started an information hub page for other Moms going through the same thing:

HOWEVER, we're going to a birthday party this weekend, and I'm very concerned. Luckily Logan isn't into food too much, but they're serving pizza and that's one of Logan's favorites! I do have gluten free pizza crusts, and I'm planning on making him one to eat at the party- but I'm nervous! Hopefully he won't have a problem... I'll keep you posted.
