I have only read a couple of the responses but my thought on it is yes I would be a little upset if I had a daughter and that happend and I would be very upset if it was my son who did it. I do have a 6 year old boy and he has never done that but I have a 3 year old nephew who is so proud of his pee pee and wants to show people and I know that he is not abused in anyway. Yes I would address the mother about it for the fact that she should be aware of it, but to some of the responses have you ever thought that when the little boy said don't tell because he would get in trouble for the fact that the parents knows he is doing it and trying to break him from it so yeah he knows he would get in trouble. I don't know all of the situation so that is why I say I would say something to the mother so if something is happening that should not be happening she is aware that you know he is showing it. I also know that my sister would be devestated if people thought she was abusing her son. She knows he does it and he gets in big trouble when he does it. As far as the boys will be boys yes they will and that is I think part of it but it is us that has to teach them what is appropriate and what is not. Boys and Girls are very different not just in the body parts either. Hope this helps and Good Luck!
