<<Disclaimer: Verify this information before applying it to your situation.>> You could almost be describing my son! Tom's 13 now, has been on meds for ADHD since he was 6. He had a "wheat allergy" which he "outgrew" when he was about 3. When you said "elephant poops," I nearly fell off my chair. I couldn't believe such large poops could come out of such a small boy! He has also had some pretty bad tummy aches, once when we ended up in emergency because he was so doubled up in pain. Tom's not on a GF diet and has not been diagnosed with celiac. I bet he has it though. Unless he starts having symptoms, I doubt we can make him adhere to a GF diet. Pizza is one of his 2 major food groups. Good luck with your little guys. I sure can't explain the relationship between ritalin and the constipation, though. Tom's never taken a "vacation" from the meds although his MD is suggesting it. The thought of it really scares me!
