I have two DC (8 and 5) both currently having issues at school with other children being horrible.
DD is in p1 and she is dealing with two girls taking against her, saying mean things and getting all of the other girls to leave her out.
DS is in p4 and dealing with one boy telling blatant lies about him to get the other kids to pick on him - stuff like DS actually contacted the creators of minecraft and got them to cancel this boys account - utter nonsense like that. (luckily it isn't working with them all but it just takes a couple to make poor DS feel like crap).
DH's approach is to tell them to be mean back so for instance if a girl calls DD weird she should call her something worse back and if a boy tries to hit DS then he should hit back harder etc.
I tend to go with the 'just ignore or tell the teacher' - although I must admit if it was me in real life I would name call back but I'm trying to take the higher ground here.
We are going to speak to the school but for now I'm looking for ideas on how Mumsnet handles these situations....
