First of all, nice to meet you! I'm so glad more people are finding this little nook on the 'net. I had similar problems with finding like-minded sites, too. It was a wonderful thing to find myself here, and our fearless leaders are great folks. We're just starting out, but hopefully, the networking will grow for all of us.

I am an adult with SPD, and I'm brand new to the idea, so I don't have any concrete advice to give you on your son's coping. However, there are several very experienced people here with diverse backgrounds that can provide you with more info. I haven't tried diet issues, either, but I know I instinctively avoid certain foods that give me problems. Luckily, they are few and far between. I definitely second beck on avoidance; if your son is avoiding something, chances are he can't filter out whatever bothers him about it. But as sensitive a parent as you are, I'm sure you are becoming more aware of those things and are helping him with that. Some things disorganize more than others. The trick is finding a good balance between organizing and dealing with the things you can't organize, like "real life."

I look forward to hearing more about you and your son, SPD stuff, ADHD stuff, and just plain old life stuff. I hope you have a chance to enjoy it here.
