What Behaviour/Reward System do you use?

[gigglewiggle]

I am back at the stage where ds needs to be encouraged to behave again (he is 5).

I havent used behaviour charts for ages so have just printed some from www.chartjungle.com, they are weekly so i can monitor him and reward as necessary.

Thing is what do i reward him with? i dont want to reward him with sweets as he isnt too keen on them so its not much of an incentive..currently im just taking certain toys/tv/pc and other priviledges away when bad and giving back when good.

What does everyone else do??
