We usually pack our food too. But it's nice to have options when I don't have my act together. I love that Jason's has gluten free bread and wish other chains would have that option.
We are in Orlando so sadly no In n Out or Red Robin for us . He won't do Asian food either. We've actually been working in therapy to increase his food options and he's come a long long way but still very limited.
My son is autistic. We transitioned VERY slowly to gluten free which made it easier for us but I suspect that's why we didn't see any significant behavior changes. But every time we try to add it back, we see huge changes in behavior. Meltdowns (which is actually not common for him), "spacy", hyper, and emotional. We even did a test once where we didn't tell his teacher. She wrote me a long e-mail telling me she had never seen him like this and asking what was going on. Having that independent confirmation told me that gluten really does affect him.
We'd actually like to be able to add occasional gluten back in. He's 4 now so he doesn't really pick up on it yet that his diet is "different." Since we're pretty sure he's not celiac (doesn't seem to have a problem with cross contamination and we've been able to do very minimal gluten without seeing any effects), I'd love for him to be able to have the occasional "cheat" with his friends.
I don't know about the cookbook, but love this website: www.chocolatecoveredkatie.com. All her recipes are vegan. She is not gluten free but every recipe I've ever seen her publish either is or includes modifications.
I'm so sorry that you got sick! We go to Babycakes a lot as we live in Orlando. But my son has a gluten intolerance related to his autism and not celiac. Cross contamination doesn't seem to affect him.
I wonder if they use an unusual flour or other ingredient that you are reacting to.
