So what is the difference between ADD and ADHD, then? I thought the H (being "hyperactivity") was the one where they bounce off the walls. Which would be my daughter, rather than my son. Her teachers have been commenting this year that she seems to be upside down a lot, and she falls out of her chair regularly. She's always rocking and bouncing and rolling around upside down when I'm trying to get her to do her homework, and apparently it happens a lot at school, too. But my son isn't like that at all. He's more of a lump.
