Through a gap in the covered windows, whilst the children were lining up to leave. I witnessed my DS6 do something to the hair of a little girl in front of him. She was smiling. I thought he was combing her hair. It was obviously a gentle action. I then saw an assistant snatch away what was in DS hand, point her finger in his face, then pull/tug a pinch of his hair!. I was gob smacked. Now DS is no angel and has been in big trouble at school before. I spoke with him, he said he was putting a sticker in the girl's hair. The assistant pointed her finger in his face (approx 10 cms from his face)and told him not to do that again, then the tug/pull of hair was because 'you could hurt her hair whilst taking the sticker out'.
Please, I feel this wasn't right. What exactly are teachers and their assistants allowed to do to a child. I know one of the assistants smack/tap him on the arm when he isn't listening. Although this just doesn't sit right with me. What do you think, and how would you approach this, if you did.
