My DS has just started school from pre-school so they all know each other. he is a softy and only child and devoted to one little boy. ( this little boy is a twin other one is a girl). They were inseperable mainly 'cos there are only 10 in class and there are only 4 boys. Other 2 boys are much younger. Today he came home devastated as the other boy had run off in the playground and said he wasn't his best friend any more and another boy was. This is probably his first rejection and I was shocked at how badly he was affected. I know this is part and parcel of school but need some help in what to say to him. HELP!
