Hi J.:
When my kids were small, I made up a chart showing who was supposed to do what chores for the week, and put a gold star when they had done what they were supposed to. Who-ever had the most stars they would get a special treat, example we would do what that child suggested they wanted to do for the day within reason ie, if they wanted to play a certain game, we would play the game. Or if they wanted to watch a certain tv show, we would do that as well. If it was warm outside we might go to the park, the zoo. Something within your financial budget.
Maybe they would choose what they wanted for dinner, like there favorite or order in a pizza, go to McDonald's something like that.
My kids loved it, but that was along time ago. My children now have children.
Hopefully these ideas help.
