My ds9 has been unhappy at school. Long story but group of friends split up as 2 butted heads- both parents says other was bullying. 1 left school. Other stayed- he is a TA s child. Now this child is upsetting mine- low level stuff, not really bullying i suppose but little things. Latest is looking through ds test and pointing out the 'easy' things he got wrong- not in a nice way. I want it to stop but its really low level-tripping ds up etc, would i be silly to talk to teacher or his mum?
