useful "bribery" technique

[miggy]

Mine have been on holiday for 3 weeks already and bedtimes have become a nightmare as "we dont have to get up for school in the morning" except they still wake early and are then evil!
Today I thought up a new trick-everyone in bed by 9pm gets a sticker, 10 stickers gets a reward. Rewards are chocolate bars in a carrier bag, each has a sticker on it with rewards including swimming trip, trip to legoland,cinema visit,play board game etc etc, (all things we would do in the holidays anyway!).
Tonight all in bed by 9-no arguments-even asking if they can have 2 stickers if in bed by 8pm tomorrow!
