Same here re: smacking essbee, except mine done it to DS1 once for laughing
The stickers didn't work at school at first because the teacher never told us what he got them for, but now that she is he seems to get them more and we can do the whole praise thing at home too. Also he got a "pat on the back" award on Friday for helping sort out the headphones and that's now stuck to kitchen cupboard door
What I've done is went to Stationery Box and bought a hardback notebook and am sticking his stickers in there with the date he got them and what he got them for, makes me smile to go through it and lets him see that we're not here just to nag him
Also we're going to take a look at how we do things here when he's naughty as we've not been consistent or issued threats we have no intention of carrying out (such as binning all his toys if he doesn't tidy them up)
Still a long long way to go here as he does seem to have a lot of anger inside him sometimes, but he has definitely got better than he was
I'll send you my msn addy through contact another talker
