Gluten free bread doesn't taste the same but it can be pretty fulfilling. We did GF for a few months prior to GAPS and in hindsight it was too easy to add lots of processed crap and "fake food" by trying to substitute wheat.

Have you read the GAPS book? You'll love it- will really help explain what is happening to you and your son. Best of all it treats the cause and will heal you, rather than just reducing some symptoms while you're eliminating foods.
