K.D.
I have 3 nephews with ADD. I agree that it is overdiagnosed today -- due to parents not asking their kids to concentrate on anything (like any skill, concentration CAN be learned). That said, don't let your doctor go for an easy diagnosis. Make him discuss it with you, and if he does say she has ADD, make sure you get him to explain WHY he gave that diagnosis. What are the symptoms that he thinks fit? Could they be related to something else? (in my nephew's cases the ADD is a side effect of a rare genetic disorder that they all share) Are there any solutions you should try first (like diet or behaviour modification) before medication?
ADD and drugs are an easy fix for doctors to diagnose, but unless that is the real cause of your daughters issues that diagnosis won't help. Good luck to you!
Just had to add -- there's been a new study released recently (that I just read about today) that links ADD relief to recess. Does your daughter's school have recess so she has breaks to "get the wiggles out"?
