My daughter has been having problems with this at school and it seems like the school staff will do nothing.  My daughters father died in October 2012 and a boy at school was calling her and her friend a whore and asked her " whats a matter daddies girl, don't have daddy to run to anymore", so she left play practice because she was upset and she got kicked out of the play and not the other boy. The play director went on to write an email to another of the school staff downing my daughter through the whole thing. What are you going to do when the teachers start on your child and no one will listen!
