Being thumped/kicked- help! (Christie please read as well!)

[Jimjams2]

Putting this on here rather than ttr in the hope that people like christie used to challenging behaviours and strategies will read it as well

Yesterday, ds1 started thumping me, and occasionally stamping or kicking an outstretched leg. He's bored. There's no trigger, he's not cross, not trying to hurt me. He's done it occasionally before, but more in passing iykwim. He thumped ds2 on the head as well. He's hitting pretty hard. With the wrong angle the stamping could break a bone, and he's thumping quite hard. I'm a bit concerned he's going for siblings as well.

The trouble is I'm back to the problem of having no punishment. I started by putting him outside the room, which he didn't like the first time, but then found vaguley funny, this morning is finding highly amusing. I've tried turning him away in a bored way, but he sees that as a bit of cat and mouse and part of the game. I've tried saying "no" obviously (found that very funny). Shouting. Funny. I've tried saying "ow- hurts mummy"- he thinks that's funny.

Any ideas, I assume (hope!) this will stop on return to school when he's kept busy all day but could do without a few more weeks of it.

We've always had a huge problem with reinforcers but certain foods have always worked. We don't treat those as R+ any more at home. DS's biggest R+ is social contact which can sometimes mean vile behaviour like spitting, its contact and interaction isn't it? I have been told by a know-it-all mum at DS's school that if we just worked hard enough on finding reinforcers we'd he successful, grrrrrrrr stupid cow!
Maybe more physical activity but that's so hard to provide at home. I still haven't bought DS his exercise bike that I've been thinking of for some time Got him a free standing hammock for his birthday but haven't put it together yet I'm going to put it in his room if the weather stays as it is now (lovely imo btw!).

ha ha send know-it-all mum here, she's soon get used to the "am i meant to be interested in that?" look. DS1's biggest enjoyment is from being naughty and the word "broken". He loves the word "broken" for some reason and dissolves into giggles as soon as he hears it. He pronounces it "arreee" though. Hmm perhaps "no hitting or mummy won't say broken again".

DS used to like it when I did the Makaton sign for "broken"! Maybe you should use the sign (like you're holding something in both hands and then break your hands apart) but just start it and don't finish it unless he behaves! You'd have to show him the whole sign to start with though.

Thanks Christie, my sons class has recently changed from mld to sld and it is not a smooth ride.
