An hour of aerobic activity does for attention/hyperactivy what a 4 hr dose of ritalin does.
So even if ur kid is diagnosed-seek alternatives. Some of them rock.
We send our 5 year old to run the fence line (1/2 acre fenced). She times herself and tries to accomplish weird tricks like jumping over a log or doing a somersault along the way. The dog lOves having her to run with.
Then she comes in and knocks out an hour of school work with no issues.
The 13 year old and I get up and hit the gym before class. In the afternoon he will chop wood, run the fence line, practice unicycle, bike to the library (3miles) etc. (not all of them every day-just examples).
