Strange behaviour 17year old son

[mumple1]

Does anybody elses child behave like this. He played atune on the piano, asked me to sing along, i couldnt remember wordstold me i did, ended in a big row kept telling me i did when i didnt wouldnt let it go. Starts spitting banging crashing threatening etc. Any way he calms down and comes to say sorry 5 mins later , gets upset because i dont tell him the right reply. He tells me what i should say to him!!! then i have to trythe reply againwith the right tone of voice. He is very hard work.

Does he do this with others? I would just treat it like a 2 year old tantrum and ignore. Go out of the room and tell him you will talk to him when he has calmed down. Has he been diagnosed with SN of some sort? If so my response might be different.

Good advice. Model calm behaviour by leaving the room, re what exotic said. Perhaps later when he's calm you can talk to him about how to cope with feelings of frustration and anger?

Yes, exactly like a 2 year old. Leave the room, ignore, don't engage but make sure that you discuss it afterwards. I feel there must be a back story, he can't suddenly have started having tantrums at 17yrs.

Some of that behaviour sounds a bit like someone with OCD - the wanting you to repeat stuff if you didn't say it in the right way. Has he always been a bit like this, or is this new behaviour?

What is he like at school? Does he have friends?
