I totally agree with Hammilton. There is no way that a 5 year old child can demonstrate hypersexuality on their own. A child that age acting in that manner would be classic sexual abuse signs. Sexual behavior is something that is learned. In adults, yes this would be a symptom, but not such a young person. If I were you and I was being told this, I would go ballistic on that doctor. What is he/she thinking? I am curious though, what are the exact symptoms your daughter is displaying? Perhaps you could get better advice if you shared them.
