None of my children had ADD, but my wife has been running a licensed home daycare for almost 25 years. I have seen all kinds of kids and all kinds of treatment.
Diane's (aussiew) advice was the best so far.
Your best route right now is gathering information. Good luck!
Check out this web site for some ideas and advice. Do not rush into anything, especially medication until you are sure all reasonable alternatives have been investigated.

"If you decide to have your child assessed for ADD, do NOT use any school personnel or anyone connected with the school system because they are biased. Unfortunately, the public school system is rewarded by having difficult children labeled ADD in three ways.
First, the medicated child is easier to handle and less disruptive.
Second, the school receives money for each child thus labeled if special ed services are requested (that's why you probably can't get special services like tutoring unless your child is officially diagnosed with a learning disability).
And third, medicated children may do better on standardized test exams, making the school administrators and teachers look better. Long-term studies, however, show that medicated children do not actually learn more in the long run, even though they get better grades.
So while it is in the school's self interest to have your child diagnosed ADD and medicated, it may not be in your child's best interest. Parents should ultimately make this decision, not the school or even the doctors."
