Hope you have/have had a relaxing bath Essbee. You asked (way down) about our positive rewards system. It's just that we use the pasta jars solely as a positive reward system. It's so visual, and he can look in the jar and say "Look at my jar - see how good I've been this week!" The misdemeanors (sp?) we deal with separately, in a way that isn't necessarily recalled for the rest of the week iyswim, because that approach doesn't seem to help him.
So I may set him a specific target to earn a piece of pasta; say helping with a chore or getting up/dressed without me having to hassle him ... Or I try to 'catch him/them being good' and put a piece of pasta in when we've had a pleasant meal without them winding o-a up or similar.
Essbee, I'm sure you're familiar with all this stuff anyway. It's just that for us pasta jars work really well, but they don't work well (for us) if used negatively.
