Possesive daughter over her friend

My daughter is 5 tomorrow and is having some issues with her best friend. They go to the same school and play often in the week together.

She is getting very angry when her friend sits with another person at school and if she has other friends. The teacher stated that it is getting worse and she is getting meaner to her friend.

I have already spoken to her by herself and with her friend together. I have told her that it is fine that her friend has other friends and she should try to not get frustrated and play with her other friends at school..

What should I do?

Your message to her is right on target. Now, in addition to that, let her know she's entitled to feel whatever way she wants about her friend having other friends, but she may not mistreat her friend. If she does, discipline her and be sure they are doing that at schol as well. A reasonable tactic would be a ten-minute time out for any mistreatment.

Maybe she also needs some other friends.  If she is only playing with this one friend at school and home (playdates), you and her teacher should encourage her to play with one or two other girls. Invite another girl to your home for playdates so that she can see that her best friend is not the only friend that she has.
