My daughter is 7 in second grade. She has a friend at school who is also in her dance class. The friend is very nice at dance class and wants to come over for a play date or a sleep over but at school my daughter says she won't let her play with her and her other friends. I suggested she ask some of the other kids to play but she says she doesn't like to play with them and only wants to play with this girl. Is this something I should just let her work out? Or should I mention it to the teacher or the girls mother? Or should I try to schedule play dates with some of the other kids? Not sure when I am to intervene if someone is being mean at school?
