My DD is in yr 1. She has a best friend who she is fixated on. She loves this girl. Her face lights up on seeing her. Most of our dolls have been renamed in honour of this girl. They play together every break and lunch.
Sometimes DD comes home upset because this friend has been mean to her. It's nothing huge but it's ongoing. The girl tells her she can't run properly, that she is a baby because she can't ride a bike, that she mustn't play with other girls, that her toys are not as nice as X's toys. I have heard the girl say many similar things when playing at our house so it's not DD making it up.
I've tried encouraging DD to play with others but she worships this girl despite often being upset by her. My heart sinks when I think of this relationship defining her formative friendships. Any ideas for how to handle this?
