OK, rockinhippy, I see your point. But wouldn't one need to bed this system in over a longer period of time? If you've already got a stroppy child the last thing you want to do is deprive them of something because then you've got a stroppy child with a sense of added injustice. (I can see how in a longer term it's a reasonable approach
Yes you are right to a point learnandsay but IME by that age they have enough understanding of the concept, that a little chat & warning that they will lose X Y Z if they don't toe the line & fly off again
Also I've seen it happen where the incentives actually become a bit of a noose around the parents neck so to speak - bright DCs come to EXPECT an incentive for every new task & will kick off if its not offered - & with them being at an age where starting taking on chores etc should be the norm, IMHO its a bit of a dangerous road to go down.
Not against incentives all together though, DD knows if she does well at School, or should I say always TRIES her hardest, she gets to choose a gift after parents evening - so I think for long term goals they can be a good - as in life, you work hard & do your best for a long stint, you gain promotion, degrees or whatever, but I just don't see it as a good plan for smaller more everyday things, IMHO it sets up unrealistic expctations
