Good Lord, Is There Anything That DOESN'T Contain Wheat?

Seasoning for hamburgers has wheat in it.

Soy sauce has wheat in it (this I knew) so anything that is made with soy sauce, like pretty much ALL Chinese food, contains wheat.

Cream of chicken soup has wheat in it.

Frickin' CORN flakes have wheat in them.

My baby is living on a diet of vegetables, fruits, rice krispies and rice chex plus whatever I can bake gluten-free for him in the limited time I have available. There are NO gluten-free foods available in Tooele, and we can't afford expensive stuff anyway. He can only eat soft foods because he has no teeth (although all indications are that this condition is about to change).

Any suggestions?
