This might be quite long.
DS (5, moderate learning difficulties, practically no speech) attends SN school. He has, for osme time, been pinching and biting his friends/ classmates. He used to do this a lot at pre-school (mainstream) but it calmed down when he started school, now picked up again a lot.
This is not a behaviour we see at home, and i think it is related to his general frustration at not being able to communicate, rather than any spite or 'wanting' to hurt IYSWIM.
When DS hurts a child, teacher sends him for 'time out'. (a mat to one side of the room). Plus yesterday, she said he nearly missed a trip they went on as he was on his last warning before they left, and wouldn't have been allowed on the trip as punishment. This seems really harsh to me, and i am also questioning the idea of 'punishing' him. It seems to me that a) they've been trying this for nearly a year now and it hasn't made a difference so is it really working? and b) as its related to frustration its a coping mechanism of sorts and it seems unfair to punish him for that. Is there another way?
Really don't know what to do about it though. I know I need to talk to the teacher but don't know what to say. Or should we be seeing someone else? Any advise would be really greatly appreciated.
