Yeah, think I'm gonna back track on the whole not associating it with chores thing LOL. having thought about it.. there's no other way really to teach the whole earning thing at the moment. I think the thing that scared me off it was I've seen so many kids refuse to do anything extra unless they get paid. How do you avoid that? Do you have set chores? or is it for general co-operation and helpfulness?

Hmm... your coin thing could be good Astrid. DS back chats at the moment, and when he's upset says horrible things like "go away" or "kill you" (and is teaching his sister!!) so perhaps once he has a bit of a grasp of what his own money can mean to him, this might work for us in some way too. Stickers don't seem to mean much to him and he loses focus on charts that move back & forth and don't seem to get to the end LOL. Tried it for getting him to remember to flush & wash hands after using the loo.. but it seemed to constantly go backwards LOL so the chart just didn't seem to work. But if he twigs at the concept of money and what it can mean for him, it could well work as a 'star chart' for us too.
