How do you deal with nasty girls?

[Mammawilson]

Year 8 Daughter is receiving some low level consistant nastiness from 2 girls who were her best friends, nothing huge but they play on the fact she wont stand up for herself.
Daughter isnt that bothered, she has the view of kill them with kindness but that seems to fuel them still being nasty to her.
Examples: telling her not to message 'k' to them, saying stuff to her under their breath etc, mainly low level stuff in that way.
The main issue is me, i want to go up to the girls, scream and swear at them, im so full of anxiety and rage at the way she is being treated i dont really know how to deal with it in a calm manner, i dont want to over react but also dont want to not react enough

You can’t change their behaviour. If you report it to school they’ll just use it a fuel and not change their behaviour.

Could you encourage her to make some new friends? Invite them over for dinner/take them out/sleepovers.

These girls will probably fall out and then one will try to become friends with a Dd again, then get back together with full force.

Try to boost her confidence by getting her more involved with sports?

Thanks, she already has a new group of friends so doesnt seem to overly hurt by these girls, its mainly trying to find out how parents deal with the anger of how their children are being treated. I feel lucky that she seems to be dealing with it better then i am

You have to swallow your anger and frustration I’m afraid. Be thankful that your DD isn’t too upset by this behaviour and relieved that she is dealing with it maturely on her own. No need for you to step in here at the moment by the sounds of things. Perhaps just remind her that you’re there for her if she needs any advice/support. Part of them growing up is being able to handle situations on their own without parents getting involved.

how parents deal with the anger of how their children are being treated in the nicest possible way - it's not about you...if your dd gets wind of your feelings she will not discuss these matters with you. I know a family that has banned half of dd's friendship group visiting their house on the grounds that they don't like the way they treat their dd. I want all my dd's friends around my house - I want to know them.

I have told dd, I am here for advice not judgement - friendships come and go, they fall out over small things - be led by your dd - if she is not bothered then drop it.

Thanks all

Seconding @MaxAmount - when i was 14 i had a major falling out with my best friend, it was very upsetting, and i told my mum all about it. Eventually we made up, but i was never able to have her round to our house again because my mum despised her. Very awkward all round.
