DS is bright, funny, sweet, kind at his best. But he doesn't do well with frustration and is quick to throw things or lash out if he gets upset/frustrated. He's already spent an afternoon in the head's office after lashing out at his teacher, and yesterday was sent to sit in the corner of another classroom to remove him from his. At his first class birthday party he pulled off the birthday boy's glasses, and the other kid was understandably upset. He's also started having accidents at school again, which is usually a sign that he's unsettled. School say it's nothing they haven't seen before but that his behaviour is also on the extreme end.
We did have similar challenges at nursery, so this hasn't come out of nowhere. I'm so worried though that he's going to get a reputation as the naughty kid which might follow him and which he might try to act up to. He loves a lot of things about school and was very ready for it but also finds it 'too strict'. Has anyone got any advice about how to help him manage these frustrations and learn that he can't respond that way? The school uses a breathing technique which we're going to introduce at home.
