About a child who isn't mine. They said to me (outside school) last week that child x was horrid to them every day, called them names, encouraged others to - I volunteer a couple of times a week at the school and all the kids know me quite well.
I told their mum and said I thought she should have a word - child x has history with quite a few children in the class (including mine) of low level bad behaviour (I hate to call it bullying when they're so little but that's really what it feels like).
Is it my business to mention to the teacher how upset they were about it?
