To ask you how to help my DC (age 10) deal with school bullies and also how to not get angry when said bullies parents all socialise together?

Long title - but my child is now being taunted at school by two children who have previous form.
Reached a point this weekend when my child was at an adventure themed birthday party and at that party these two children attempted to harm my child by wiggling the ropes she was climbing on. Obviously they were safety nets but I think this behaviour is awful.
My child is quite resilient - they have coped with loads of things but what do I do.
These two children have bullied others and I was surprised they were invited to this party.
Now they appear to have turned their attention to my child who has avoided them seeing her friends suffer.
There was a sleepover a few weeks ago and behaviour from these children resulted in them having to see the school's headmaster.
What troubles me is that these children have bullied other children and yet the parents of the bullied kids are so ott on Facebook to the parents of the bully children. For example -One of the bullies' mums had a birthday the other day and the mum of one of the bullied children was all kids emojis etc etc.
I can't do anything about that but what can I do to stop this happening to my child.

I'd speak to the head again and ask to step up their support and safeguarding as it's not worked - split the bullies up, have the parents in and tell them to work with the school to stop the behaviours. Also perhaps the parents of the bullied kids on their own behaviour and techniques to help their poor kids

Im so sorry you and you child is going through this. Speak to the paremts of the bullies and tell them to sort their kids out. Some people drag their kids up with no morals or consideration for others. If your child is getting hell from the two bullies then make the paremts life hell if they dont sort it out.
