Hi Paul. We have a 13 year old DS who has PDA. He is aggressive and violent. He is on a reduced timetable in school because he is so disruptive. He becomes aggressive and violent when challenged.
He pushed me over last year and I hurt my ankle. It was the latest in a long line of violent outbursts. He had smashed up 2 TV's by throwing a remote control, Threw my vacuum down the stairs, punched my full length mirror which had shattered, there are dents in our walls and our doors are hanging off their hinges from being slammed so hard.
I snapped. I called the police. An officer came to the house and spoke at length to my son about the serious nature of domestic violence. Although I had no intention of taking it any further, I was hoping this would put the frighteners on my son. He simply sat on the sofa opposite the police officer looking bored and occasionally smirking. Words cannot express the sheer embarassment I felt.
I know you are reluctant to call the police and I personally woudn't. The police are there to uphold the law and if you don't want your son arrested (which presumably you don't) then I wouldn't bother.
My son (like yours) does not respond to punishments and cannot process information to understand consequences. We have had no choice but to change how we parent him.
We have identified triggers (raised voices, direct requests) and things have improved in the last couple of months.
We have limited his boundaries to the bare minimum such as he is to be home by 9pm on a weekday and 10pm on a weekend. If this changes he must call us.
I have given up on all the 'normal' stuff we want our kids to do such as tidy their rooms / do homework etc.
I tidy his room when he is out and ensure his laundry is done. When we need to talk about something I word it in a way where I am appearing to ask for his opinion and letting him think he is in control of situations and their outcomes.
If he starts becoming verbally abusive, I simply and calmly say 'I will talk to you when you are less angry' and turn and leave the room. There is no point in interacting when he is in a rage. Would it be worth you saying to your son something like 'I know you love playing on your PC, but sometimes we have to try and find time to do XXX - what do you think?' Or 'I know it's important for your laundry to get done, if you're finding it difficult to put them in the basket in the bathroom, maybe you'd like your own laundry basket in your room?'
My son also started smoking weed as it says it's the only thing that takes away the anger and rage he feels. We are heart broken.
You have to also remember that all these rages and moods are exaggerated with puberty.
My son is massively moody and a right PITA but his angry outbursts are far less frequent.
As hard as it is, you should not take anything personally. The names which I am called is shocking, but I tell myself to take it all with a pinch of salt. He still needs to learn how to articulate and control himself.
Keep us updated. May be contact the National Autistic Society for advise with strategies which may help?
Good luck
