Reward system for very challenging 3 yr old?? Please!

[amunt]

Everything from going to the toilet to eating meals, getting in the car, getting dressed is a major effort/battle for us. He is pretty much resistant to everything that is somebody else's will.

Would be incredibly grateful if anyone who has had success with a reward system for an unbiddable toddler could share it.
Thanks

Beads in a jar.

Find the right currency: TV time, game, small toy, whatever. We used lego.
Find the right size of jar/container and beads/tokens. Star with small jar and big beads for quick positive feedback. As they become more compliant or as their understanding and maturity permits, make the jar bigger and then the beads smaller.

Keep the jar out of reach

So day 1 would go: chose breakfast and ate some of it - bead, hugs, well done! Got tshirt on without a fuss - bead, hugs, well done! Helped to put some toys away - bead, hugs, well done! Jar full! Small reward! Empty jar, start again.

Until they get the hang of it, the introduce more beads/larger jar. Then make a point of explaining that beads can come out if the jar for poor behaviour. We did one warning only, then remove a bead if behaviour continues.

If you find the right 'currency' they catch on quite fast. My DS really wanted to complete his lego model and needed the pieces! Resist the urge to remove too many beads at first and give lots of opportunity to collect them.

Good luck.

Brilliantly explained idea.
Thanks
