Constant tanrumming throughout the day, god help me

[himynameisfred]

My son has been tantrumming since about midday, it's 4pm now.
(has autism, is nearly 5, not in school and has next to no speech).

I've put him on the stairs, waited for him to calm down, given him a hug and drink.

He's started growing and roaring demonically after just a few minutes every time.

I gave him some dinner and put up with his growling/roaring until it turned into screaming. (he seemed to have a problem with the way his little brother was eating pizza at one point, flipped out because i sang along to something at another point.)

I can't take it, I'm gonmna have a heart attack.

I feel like I',m going to lose it listening to another person constantly in distress and there's nothing I can do. No amount of affection or distraction I can give him to make him stop.
It's as if he's being stabbed constantly by invisable pins and he's taking it out on us.
So I've taken the precaution of putting him back in his bedroom before i kill someone as his room may calm him right?

He screamed in his room for 1hr and a half I would estimate before we had pizza.

He is now screaming in his room again.
I've turned some music up for me, my toddler and my unborn baby so we can all just remain calm.

Can anyone assure me I'm doing the right thing?

Or we could just take bets, what will happen first? he loses his voice? or a neighbour calls the police?

Update;

DS spent around 40 minutes in his room doing an impression of the excorsist, before taking a breather.
I went up and took him out he casually said hello. No signs of tears or red eyes or anything.
He had literally been screaming in pure anger for that long.

He's now playing in the bath with his little brother.

I gave him his present from Lush, a fizzing frog which makes the bath green, which he enjoyed. Thought he was going to lose it full on when I couldn't give him the frog back, after it had disintegrated in the water, but he accepted a replacement toy and moved on (phew!).

All good so far, wish I could calm down and relax myself now

Poor you and poor little Fred. It must be so frustrating for him not being able to articulate the problem.

I keep posting about it but I recently read The out of Sync Child by Carol Kranowitz. It's about sensory processing disorders. I found it very useful in understanding where ds is coming from. Though he still drives me up the wall at times!

Ps a bath and lush fizzy is just the sort of thing Kranowitz would recommend.

oh really.
I'm going to look into that.

Glad I'm not the only one driven mad by their bundle of joy.

The stress is intollerable.
Even just now at bedtime he was doing such jerky robotic hand movements to 'twinkle little star' had to sing it about 15 times to prevent him having a meltdown.
The amount of straining noises he does constantly. I'm sitting in his doorway as I type so he will stay in bed.

He also grinds his teeth and just makes ungodly noises, like he's trying to squeeze his body through a small space constantly.

I'm going to die of a heart attack from the stree of listening to it, honestly.

Wish I could get some light sedatives for him, maybe he'd be happy and relaxed for once.

and it's begun again this morning.

I'm going to have a heart attack.
