I think like so many have already said that yes they do work. I find that on my bad days...lol reacting to Oskar's bad days - both of our days end up appalling! That was yesterday - wrong side of the bed for him I think.

Anyway, for the mostpart yes it's great! In fact I've noticed lately a lot more that he's coming to me telling me what he needs to be doing - eg: today we're at a friend's house and he was playing with a toy and I brought another out which his little friend was going to play with and Oskar immediately (as 2 yr olds will) raced to get it. I put my hand up (as in stop) and said stop, you are playing with X and before I could say another thing he goes... wait until J has finished then I can have a turn. YAY!!! YES!!! I was so proud of him. I try to explain to him why etc and I've found that to be something which works so much better than just a "do it" type of approach. I think they need clear and positive instruction as much as possible.
