Why does he do this?

[Clumsy12345]

Does anyone else have problems with kids teasing siblings? My son teases my autistic daughter so much it’s causing so much problems at home, today thought we would have a nice day and no he’s caused her to get angry and last out again, he does it all the time he winds her up constantly he is told to stop and he doesn’t listen now she’s screaming and crying her eyes out over it. Why is he constantly trying to upset her? Is this normal for siblings?

How old are they and what are the consequences when he doesn't listen and upsets her to this degree? I think all siblings argue to a degree, mine hated each other at times but would defend each other to the ends of the earth if someone else was upsetting their sibling.

No he doesn't defend her if anyone does it in fact children outside have started copying him and he loves it. He is 10 she is 13. His devices get taken but it doesn’t stop him.

No advice but my older brother absolutely tormented me when I was a child so I'd say it's normal. I think it was his way of being affectionate (maybe)
