To be worried about this for dd

[gertrud76]

Dd is in year 7. There is a girl that has previously bullied her from primary school who is now in the same high school. This girl has made it her mission to befriend anyone dd becomes friends with to essentially take them away from her.
Dd made a small friendship group, this girl has tried again to break it up.
Recently the friendship group fell out over something small, and one of the girls in the group has decided to now become friends with the bully knowing the full history with bully & dd.
Aibu to be really upset for dd about this, it feels so mean and i really worry that this bully just isnt dropping it. She is attempting to make my dds life miserable and now this new friend she had, has betrayed her the minute they had a falling out.
Really scared about this becoming a serious problem for dd and ruining her high school experience

That's very worrying I'm not surprised you are upset. I'd have a word with the class teacher so she knows the history. Encourage DD to make a wider friendship group as it would be harder for the bully to deal with that.

You can only encourage your daughter to branch out making connections outside school in after school clubs, hobbies, lunchtime clubs and make sure she doesn't overshare with the bully girl. The wider the net, the easier for your daughter if the bully keeps muscling in.

I'd definitely speak to the school about this. How big is the school? At DDs school, the year group is split in 2, with several tutor groups in each half who very rarely interact with each other. I'd see if there is a similar set up at your DDs school and if there is, I'd get her moved. If this isn't possible, the school has a duty of care to your DD. When my DD had a problem with a bully, the bully was taken to the office and told that the bullying stopped now! Bully was so shocked they did stop.
