My little girl started nursery 2 weeks ago and recognised a girl from playgroup and has latched on to her. For a few days they were best buddies, but for the last week and half this girl and her other buddies have been telling my daughter that she can't play with her and won't let her join in. My daughter however still seems to hang around her and has told me that she doesn't mind sitting watching. I have told her to play with something else or someone else but she is fixated with her "best friend" I have spoken to the teacher who advised my daughter to tell her when this girl and friends won't let her play,but she said they still only played for a little while then she was told to go away again and to watch. How do I try to convince her to do something else?
