I have noticed that my 4yo daughter has a VERY hard time with the feeling of rejection. The times she has broken down the biggest is because of rejection, times where her fellow friends have said - “I don’t want to be your friend anymore” “I don’t want to play” “i don’t want to sit next to you”….it has happened at playdates and that's when I notice the breakdown and very hard recovery. Help! I’ve bought books and stuff, but nothing seems to work. What do you suggest?
