Personally, I do not think this is a problem. It is normal. I have a son and a doughter and I expected it to be more common with my son, but like you, I have really had the issue more with my daughter. As long as you have asked all the "questions" and she knows that it is her body, I do not think it is a issue. I would be sure she understnads it is something that is private and stop focusing on it. We live in a very sexual society. Kids see these images even when we are trying to protect them. They are everywhere! I hope I am not to blunt. I think you have done everything the right way. Hang in there!
