9 yr old girl Masturbating

I wouldn't tell her not to do it, but it may be necessary to give her guidelines as to where it's appropriate(bedroom, bathroom) and be sure she understands it's private and she can discuss it with you, but not at school. And also, that it's personal and should not be done with other people. I've always found being honest and open about these types of things makes it easier for my kids to ask me questions they might feel uncomfortable about if I was less open. Hope this helps.
