Hello,
I have the same situation here with my 8 year old. We do the GFCF diet even though he is not on the spectrum. He does have issues that are similiar to the spectrum issues. He is more ADHD and has learning delays. Thru our journey of trying to help him, we discovered he is celiac and colitis. This causes symptoms very close to the spectrum issue. I have found that he has terrific days and hyper days. I think it is cause to his tummy being damaged. He is allergic to almost everything. (he has behavior reactions) I have him on the feingold diet too(adhd). We do give him supplements and take him to a doctor to help with his food adversions. I think we have been to every doctor in Chicago land. Diet does work. It seems hard but really isn't once you get the hang of things. Let me know if you need help. This is a long process but your child is worth it. We have been doing the diet for 3 years. Food seems to be the biggest factor if he is have a great day or not. Chemicals effect him so we are organic. I discovered that he is not allergic to chicken or eggs. He is allergic to the antibotic they feed the chicken, beef and pork. Sorry for rattling on. I am trying to tell you what I have discovered thru the years. We still have a long way to go:)
