Often Anger is just a way that Autistic kids express themselves and it may be the Only way your child knows how to React .......
Ecspecially if he has a partially limited vocabulary or is completely Non Verbal.
.......Although Anger is usually a sign of being Upset Autistic children can just be feeling Over Whelmed or Over Stimulated .Even if it means He has had Too Much Of a Good Thing like Too much Excitement at a Friends Birthday Party or Too much Sensory Stimulation from lots of Physical interaction from Family or Too many people Talking or Too Loud of Music at a Family Bar B Q and Get together.
Even though it might take Your Son some time, you want your Son to be able to start learning how to Decompress Himself with very little Help or Coaxing from someone else as possible because he wont always have someone else around to Help him do that.
Usually an activity with a particular Sensory Item helps.....like a Squishy Ball or some Play Dough to Squeeze, a Weighted Blanket to Lay Under,
a Chair to Rock in, or maybe just Listening to a Favorite Song or Nature Sounds on the Radio.
But Before ANY of that can begin to Help the situation your Son needs to learn
( if he is able),to REMOVE himself from the Person or Situation that is causing the Aggitation.I don't know how old Your Daughter is but if she is Old enough to learn when her Brother is starting to get Overwhelmed or Angry then she could and (Should) also be taught to watch for Social Cues as to When her Brother is on the verge of Losing Control and lashing out
Physically.Knowing this will Help your Daughter learn how to help DeEscalatel a Situation by Keeping Calm then Walking away and Telling You Calmly and Quietly that her Brother raised a Fist at her.
Try to keep in mind that a Change in Activities or a Change in Surroundings can also help.a great deal.
Also I don't know what Level of understanding your Son has, but there is a Book called, HANDS ARE NOT FOR HITTING......
I am Not sure if there is more than one Author with that Book Title because I have heard more than one Version of the book ........but it is a Perfect way for Your Son to learn to find Other Nicer things to do with his Hands.

When my son was that age, I made him sit on his hands a few minutes to learn not to raise them in anger. It worked pretty well until the hormones took over. However in his late teens all that aggression broke through and he really did hurt me badly. I did find that sensory activities like swimming and running/trampoline play really getting him tired out helped with excessive aggressive energy at that age.

Good stuff RedRhino. Years ago I used to take both younger children swimming 3x a week and it worked wonders.

AMEN to That.
I can't tell you how Many times Medical Professionals....
Counselors, Psychologists, Doctors, And Nurses have said they had NO Idea what so ever that ANY of my children actually had Autism.
In fact they have even Argued the point with me many times......... Questioning IF Any of my children even have an Actual Autism Diagnosis at all and Wanting to know WHO Diagnosed them with Autism and WHERE they were Diagnosed At and even asking WHEN they were Diagnosed as if there was Doubt that an actual Diagnosis was made.....?
In fact one time in particular Really stands out in my Mind ........
A Pediatric "NEUROLOGY" Nurse at COOK Childrens Hospital in Ft.Worth,Texas actually told me my Children did Not LOOK like they had Autism.
Other Doctors and Nurses at the Same Hospital have stated that my children are TOO Well Behaved and Well Mannered to be Autistic........and these Remarks and this Mind set came from Medical Professionals.....who are College educated and are supposed to be Specifically Trained and More knowledgeable about Children because COOK CHILDRENS HOSPITAL in FT. WORTH is a PEDIATRIC SPECIALTY Hospital with PEDIATRIC SPECIALISTS who are Not supposed to be totally Clueless or Completely Ignorant about Autism because Autism is a NEUROLOGICAL Condition that NEUROLOGISTS and their Neurology NURSES should be Very Familiar with.

I have 3 children on the spectrum and it was not only the ER, my ex spouse would use them as a weapon against me. This is common and the healthcare community is not in tune with this. I've had social workers in their 20s that are recent graduates call CPS. It did almost broke me. Unfortunately, ignorance is rampant and the new graduates without children consider themselves the best parents. It is extremely difficult to deal with this. Now that my children are grown, I may just advocate for better education of these professionals in hospitals and social work positions. They seem to be troubled and have a need to be right about everything with little experience or education to go on.
