My 5 yr old girl has displayed inappropriate behavior involving her private parts on several occasions. I got a phone call from her principal telling me that she had lifted up her dress and pulled down her panties, showing her privates to a male classmate during class while the teacher was turned around. She admitted to doing it and told the principal that she had also done it to another boy at school.(or on the bus). Just a short while ago she got into trouble on the bus. She was raising her legs in the air, spredding them open and a boy hit her in her private area. After he did that she started telling him to do it.She knows that what she is doing is not appropriate and that she shouldn't be doing it, yet she still does it. I have tried talking to her, time out, (kind of)grounding her, taking away privilages...but NOTHING has worked. What should I do to make this behavior stop?!? And make her realize how serious the situation is at school? Please give me some suggestions or advice on how to handle the situation. What kind of discipline should be used? I really don't know what else to do.
