Hi, I'll try to be brief as I can. Names changed.
So my dd (9) has always been a bit of a social butterfly, always praised for being kind, nurturing, comforting to other children. Last year she was partnered up with a girl called Luna because Luna was finding it hard being back in school after lockdown. They became friends. Towards the end of the year they started playing with two other girls Penelope and Hermione. All good.
In September my dd played on the odd occasion with another girl called Ginny. Dd felt Penelope didn't like this. She said she stared at her and was whispering things but when she asked what was going on or if she had a problem with Ginny, Penelope said no.
Friendship rumbled on but with increasing incidents where dd felt Penelope was being mean but she didn't understand why.
Since Christmas this has escalated to all three girls (Luna, Penelope and Hermione) excluding dd, chastising her for things that she's not even sure what they're talking about and (dd believes) talking about her. Even a member of staff said when she brought them together to talk about it, the girls were bringing up really trivial things from years previously to show that dd was at fault.
We decided the best course of action was to not be friends with them anymore (dd had been trying to stay friends because she felt if she was somehow 'better' they would forgive whatever she'd done and they'd be friends again)
Now it seems Penelope is still making snide remarks and has accused dd of stealing from her house during a playdate last year.
So the upshot is, what do I do next? The school are aware but I know that this kind of low level, persistent stuff can be difficult to knock on the head. However, it's not OK to acuse someone of being a thief.
