Not sure how to handle this friendship problem

[Pinniepot]

DD lives next door to her friend, they are both 6. They play together most weekends but DD says friend is mean to her at school, either refusing to play with her or trying to entice DD's friends away at playtime.

Of course I take all this retelling with a pinch of salt. But it is getting DD down a bit and I don't know what to do.

I wouldn't consider getting involved if it wasn't for the fact they play every weekend and that we are neighbours.

Anyone with any advice?

I would invite other kids round at weekends observe the dynamics

They are ok. DD is a bit dominant if anything. But then at school it switches around.

Little girls are often mean to one another and test the friendship boundaries. I’d say this is an opportunity to work through with your daughter how to put boundaries in place and work through her feelings when friends act badly. It’s not a good look for a parent to take sides in ordinary kid callings out.
