My dd has just started school, and child in her class is constantly awful. Puts fingers in pants and asks my dd to them smell fingers, swears, hits and intimidates my dd. I don't want to be "that mum" and keep complaining to school...but how do I stop this behaviour? I tell dd to stay away from them, which she does and says "you upset me, I don't want to sit with you". The child's mother has yelled at me in playground as my dd is apparently being mean saying she doesn't want to be with her dc
