6 year old DS1 with Autism anger problem

[MumOfTwoBoyssss]

(I posted this on a different thread but was advised to come to this thread, I still have this problem)
I don't know what is is, I know with his autism my DS1 has no understanding whatsoever, but his anger is getting out of hand, he has (or had) a tablet that I only allow him to use once a day for 15 mins, he's only allowed access to educational games and so on, but he's recently ( if he loses a game or if the tablet freeze's or the battery is dying) he will lash out, throw the tablet across the room, hitting and kicking me and so on, he had a Tablet that he smashed ( it's had protection on it to stop it from smashing,) just threw it and it smashed, he was constantly asking to use it afterwards, he clearly doesn't understand that if you break something, you can't use it it's gone, no matter how many times I've told him he will still ask for it, then gets angry, so his nan gave him a tablet to use in the mean time, I've been thinking about buying him another one but after today I don't want to, but the one his nan gave him, he's also just smashed! I have no idea what to say to him to make him understand that if he breaks something it's gone! His anger is getting way too much, he's even broken a few of DS2 toys I got him for Christmas aswell, and he just can't understand, I explain over and over again to him he has to look after his things but he ends up breaking every thing,

Sorry I'm just rambling and I probably don't make any sense but, anyone with an autistic child, what would you do? Would you replace it? Do I punish him by not replacing it at all? Or do I just keep telling him over and over again that if he doesn't treat his things with respect, it's gone for good? He's in the bathroom crying his eyes out because I've just told him about 50 times he can't have his tablet because it's broken, he just keeps asking for it like hes dismissing the fact that it's broken and can never be used again. I know it's only a tablet but I'm running out of ideas to make him understand.

What would you do?

I've had similar with my autistic son in the past he is 7 now but when he was 5/6 he would at times become v aggressive when coming off the tablet.

Idk how other autistic children are but my ds loves the iPad/Xbox (Lego game) and because he struggles to control and regulate his emotions at times it's been horrendous when it's time to come off it.

What's helped....complete break from it. We stopped him going on it for a few months, kept it out of sight and didn't mention it. If it was mentioned by him we simply said it was broke and in the bin. When he did mention it we tried to distract him with other activities/talking about his favourite thing etc. We found repeating phrases such as ' no you can't have it', 'it's in the bin' only made him worse.
It took a week or so but he gradually got used to not having it

I will say he does go on them now and he is a million times better. He's matured, he's developed more, he's learning how to handle his emotions and accepts that he can't always have what he wants. It's rare we get any kick offs now at all.

It's something that just comes with development.

When we decided to try n let him on again (elder sibling needed an app for homework) it was made very clear to him the rules. And if he broke those rules ( he comes off when the visual timer has ran out etc) then he wouldn't be going back on

I feel it's all developmental and it's something that improves in time but you have to stick to the boundaries you set

Thank you for the advice :) this was a couple months back now, and he hasn't really improved anger wise, intact he's gotten angrier without it, he has rules but his rules are in pecs and he just will not understand, but the only thing that has gotten better is him letting me know WHY he feels so angry, his speech has developed just a tad bit more since then and can now tell me why he feels the way he feels but they're only one word answers, I help him by changing the subject away from his tablet (his nan brought him a brand new one and seems to been treating this one with way more care now) and I took your advice and started doing other activities bthat he'd enjoying, he loves drawing and practice writing so brought him a big drawing pad and writing pad and that's his quiet time, he reading books from his tablet and that's actually all he uses it for now no games are allowed unless he can follow rules which he does, it's gotten better but his anger still remains I'm afraid, with this pandemic aswell I can't take him out as he's high risk so he's been home, but I've learnt that drawing is his calm so showing him his colouring pens and pencils with his drawing instantly calms him and he'll sit down for at least 20 mins bless him thank you so much for your advice hope everything is ok with your ds too :)
