DS1 4.5 has a firm best friend and basically another child has moved in so DS1 now has to share said best friend.
Every night this comes up at bath time and his possessiveness is causing him real issues. Other than this he loves pre-school.
What should I say?
How can I help him to chill out about it?
He does loads of play days with other children but this makes no difference as he still keeps true to his best friend and seems to repel other childrens offers of friendship.
