My ASD 7 year old son has violent tantrums as well. He is high functioning but when he is in a rage he doesn't seem to understand anything we tell him. We struggle with his aggressions quite a lot but they have been less frequent. My advice to you is first of all try to find the cause of his aggressive behavior, is he trying to get out of doing something, does he want access to something, does he want to do something he is not allowed to do? Then try to be very clear about how his day is going to be, the rules he needs to follow for instance they might be different depending whether he is at school or at home. And have a reward system in place. For instance at school my son has a schedule of the activites he will do durng each day with three faces next to each activity, a smile, a straight face and an angry face. If he come home with angry faces in his chart, he gets no gummy bears (his favorite candy) when he ges home because an angry face means he has hit somebody at school, teachers included. Yes, when he is upset he hits anybody. And then he gets a gummy bear for every smiley face in his chart. At home if he hits he gets no tv or ipad or computer time. We encourange him to use his words and say "i am upset" or something like that and make him breath slowly and deeply which sometimes help him calm down. He responds a lot better if you speak to him in a very soft voice. Then again, there are times when nothing seems to work, and the hitting, kicking, pulling of hair, throwing things cannot be stopped. Social stories of what to do in certain situations that you see your child might get upset seem to work too. We are using them at school specially social stories about what to do at recess which is a struggle for my son. For nstance what to do if another kid hits me or pushes me. We tell him he has to go near a teacher and tell her instead of going to the kid and hit him back. My son is very strong and tall for his age so he can really hurt a classmate easily. Hope my words help you a bit. And if you found any other good suggestions about this, let me know.

This is my son for sure. I can control him at home but he has gotten kicked out of daycare 3 times for his violent outbursts. He hits, kicks, throws chairs, throws blocks, and ripped a necklace off of the teacher. But this is mostly an outcome if someone bullying him or the teachers being harsh with him. Good luck.

I have an older child now, but for high functioning kids, the typical disciplines like the book 1-2-3 magic, etc work well when used consistently. The behaviors often get worse at the beginning of using a discipline as they are trying to gain control they are losing.

I also have found that whatever they are not wanting to leave (like tv or video game) is a great motivator too. If they don't do what they are supposed to do, the game is on time out. Worked really well pretty quickly.

Yes! My son is 15 and does this every single day! Some days I don't know how I am going to make it, but I always manage somehow. I have had to call 911 to help me get him off me and my dad.
