I have gone GF for my 4 year old.

This website has been helpful.
I use Corn Tortiallas, as the are GF and cheap.
There are many products that always were GF.. Try to stick with them.
Rice cakes are yummy, taste like popcorn.
We have a store by us that has a lot of options at a "reasonable" price. It is still expensive. You are better off eating traditionally GF foods.
Corn Flakes-unless it is stated is not GF it has Rye in it.
We have a bakery that makes only GF products. Sweet Ali's in Hinesdale IL, you can check to see if there is a GF bakery near you.
When you make it, it goes stale fast.. cut it to portions you want, and freeze it right away. That is why most of the GF breads are frozen.
I found this article this week.

Keep this in mind when shopping and picking out products.

They both say about the same thing, one is more recent than the other.
A lot of pizza places have GF pizza for a treat. We have one we buy at the store it is a personal size and is about $6.00 so we get those and then when we order in pizza we eat the normal one. Or it gets way to expensive.
Good luck, it is a big change, but I have lost weight by going GF. And I have no regrets.
