Mine is obviously combined type (although it seems like she is actually more hyper now than she was before she was diagnosed at age 6). I think diagnosis is an issue with ADHD girls who are just inattentive. When teachers think ADHD they think hyper, impulsive, etc. Not sweet girls who are compliant and cooperative. It took us a while to get a diagnosis, partly because she was young but also because she held herself together pretty well in school and looked basically like the other kindergartners (now they have matured and she hasn't).

If your DD is wiggly or has trouble sitting still that sounds more like "combined type" than "inattentive type" although I guess it depends on degree.
