Bless your heart. I have three kids, the oldest boy has ADD, the second boy has ADHD and my daughter (adopted) has ADHD and Aspergers.
Read everything you can get your hands on and join CHADD. It's the best thing you can do. The drugs are harsh and if I had it to do over again I probably wouldn't put my kids on them.
I let them talk me into T1 which was basically kindergarten over again for my second son and wish I hadn't done that. He is very smart and wasn't a good choice.
Schools will do what is easiest for them and not in the best interest of your child regardless of what they try to make you believe. Like I said, READ everything you can get your hands on and educate yourself on this "disorder".
Many think diet may be a factor, food allergies perhaps. I would try eliminating some foods and seeing if there is any improvement. Also caffeine works much like the stimulant drugs they give and has positive effects on some kids.
Gosh, I've nearly written a hub. Perhaps I should. :o)
