I have no experience with this problem. However, I do remember a nephew and a grandson telling me about a girl in kindergarten who went in her pants and how they did not want to play with her. Their parents and teachers did not say anything negative about the little girl, however the children themselves ignored her. Is this an ingrained thing ? I don't kinow but I do know that punishment is not going to work, it will make it much worse. I would try a chiropractor is no one else can help the child, they have helped me a few times too. Good Luck and turn this over to God.
