E.S.
I haven't tried Kid Power and it sounds like a great idea, but I have been open with my kids. I have son and when he was about the same age, I found him playing with himself. I was shocked at first but I let him know that it was normal and we talked through it but I explained that no one else was to ever touch him. Not long after that we went to the doctor and of course she went to touch him and he freaked out. I then had to recant what I had originally said and told him that the doctor is there to check him and make sure everything was ok. I let him know that only a doctor could touch him and ONLY if mom or dad were in the room. This has been regular talk in our home. A couple of weeks ago he was hit in the private area and the nurse asked to look. He wouldn't let her because she wasn't a doctor and a parent wasn't present. Obviously, all these talks got through. Being open works for us.
