what rewards treats do you use???

with one of my foster children atm. we are doing alot of sticker/stamp reward charts i dont want to give food items as treats all the time as we are working on a 3 sticker/stamp chart= a treat, so that he sees the rewards quicker, as treats so far i have - a frozen jelly or frozen yoghuet stick
- extra book at bed time
- extra 5 mins awake at night
- occasionaly a sweet treat must have reached 10 stamps/stickers for this.

im running out of ideas, so tell me what do u give as a reward or a treat for doing the right thing??/

how old are they?
I know as a reward thing a friend of mums would buy those little legos? I think they're like $4 or something from big W... you'd get a little bike or spaceship or something to put together...

A friend of mine has a tub in cupboard with random little things from party blower, balloons, bouncy ball, wind up toys, lollies, bubbles, fancy straws, etc like random party favours etc.

She used this mainly for TT rewards after so many wees in toilet.

fantastic ideas...the kidlets range between 1 and 4 yrs , and a mix of boys and girls, love the curly straws idea my kids are always looking for straws :)
