We have had this m&m canister forever. Since Jolie loves m&m's I decided to get it out and use it as a reward system. We call it the naio naio, good speech sounds. Jolie still says the chinese words naio naio for using the bathroom. SO everytime she uses the potty or does her speech sounds correctly, She gets an M&M. We've had some success...pray it continues to go well.
