DD is 5 years old and coming to the end of her first year of school. She has been joined at the hip with a friend from nursery and they've had a lovely little friendship. Another girl joined their group but was for a period quite nasty to my DD. Saying mean things to her, spitting in her face and even choked her. When this happened I contacted the school and they dealt with it very well and the ill behaviour stopped. Fast forward to a couple of months later and both these little friends have been excluding my DD. She said that they left her by herself during lunch and then are picking on differences like she's not lost a tooth yet or doesn't have the same keyring etc. I feel so bad for my DD and have encouraged her to play with other friends but I'm not sure if her confidence is low or if she goes back to them because her 5 year old brain can't quite navigate the situation. She has been so sad all week and I feel awful for her (not letting her see that though). I've tried saying that it's important to have friends who are nice to you and to play with other friends but I'm not sure how to navigate this? I remember groups of 3 girls from school and it's always a bad mix.
