What works well for you? Up until now I've been very much reacting to each situation individually and trying to teach/guide rather than reward/punish but it's not working any more. I think I need something more concrete so that DS knows where he stands and I don't end up losing it 
I'm rubbish at any kind of time out thing, I suppose because I haven't done it before now, but DS just gets up off the step/out of his room/wherever and can open all the gates so I can't lock him in any more! This did work really well though, when he couldn't open the bottom gate, he'd rage for about 2 minutes, and then calm down and be lovely. But now he just keeps following me around the house and I cannot physically keep putting him back AND stay calm, so that's out.
I've heard something about a pasta jar method? Could anyone explain that to me? Or anything else you find works for your 4 year old :)
