Most of you know my ongoing battle with him and behaviour. I have always thought that he wouldn't care enough about stickers to do it, but after yelling at him again we have had a chat.
It is going to be fairly tedious, and I am ignoring the whole "praise good/ignore bad" thing.
Half hour slots all day - no telling off = sticker, telling off = cross.
Half hour may be long for his attention span, but we'll see how it goes.
Probably breaking many parenting rules and leading him on a path to murdering kittens and stuff, but meh, not getting on well any other way and he is being a git in preschool now too ("a bit of a pickle" which I translate to "a git but cute about it")
