Daughter is 9.
For most of the past 2 years she has been friends with a group of girls who are very mean, always preoccupied with who's speaking to who, who likes who, passing messages about not speaking to each other. Horrid and silly and exhausting. Just to be clear, my daughter is every bit as bad as the others. She's not a leader, but she'll follow anyone and be dreadful and thoughtlessly mean if she thinks it will win approval from the popular girls.
I was always there to talk to, and to gently advise throughout all this. Dd is lacking in confidence (not an excuse) and I do try to encourage her to feel more sure of herself, and to do the right thing.
A couple of months ago it reached a point where she was just so unhappy and anxious and she decided to not be friends with them any more. She hung her bag on a different peg in the hall and they have never spoken to her since.
She mostly reads by herself at breaktime, though she does have a friendship with a girl called T. She is not massively keen on T, but they have playdates, and have books in common.
Enter P. P is new to the school and suddenly my daughter and P are best friends. I was under the impression that DD, P and T all spent break and lunch times together.
Now it's P's birthday party tomorrow and I needed some info about something so messaged T's mum asking her (dd had told me that T was going). Turns out that T is not invited to the party and that my dd and P have been whispering about it and leaving T out all week and giggling at her. Ugh. I'm so disappointed with dd.
I was to ask for her version of events, and if it's true I'm not going to let her go to P's party. What do you think? What would you do?
