I can remember touching myself when I was little and both my daughters (2yrs and 4yrs) have done it also. I know I wasn't abused and my daughters are not abused. My ped. said that kids around my older daughters age are always touching themselves. I kept thinking she had a bacterial infection because she was itching there a lot. I am curious if you ever found out who "Anna" was though. I think maybe try to get her involved in outside activities maybe. Also, I would try to get her involved with other children.
