Thanks everyone for your replies. I must admit i was a little embarrassed about posting what was going on but it's nice to hear from so many of you and hopefully it will help others that go through it later on.

I will start talking more to Kimberley about what she is doing and helping her understand about who is and isn't allowed to touch her body. Hopefully she won't do it for long and at least she only does it at home at the moment.
