Dc has been friends with another child (A) since nursery and have been in the same class throughout. A and Dc have had a good relationship and they also have lots of other friends. In the last year another child (B) has entered their friendship group and has become very close to A which is fine but B is now apparently trying to exclude dc from the group saying that A has been friends with him a long time and he is now bored of him, saying dc can't play games with them as the game is only for a certain amount of people etc and generally being unkind. A and the others are also joining in and trying to get away from dc at playtime or barely tolerating him when he plays with them. I have told dc that they are not very good friends if they behave in this way and to find some new friends but he says that they are his friends and he wants to play with them. Why are kids are so cruel?! What advice can I give him? I've tried inviting other children around for play dates to try and give him options. I'm also fairly good friends with both mums of A and B but wouldn't want to involve them.
