ds1 is 7. we tried pocket money about a year ago. he spent it all on flipping doctor who trading cards. we gave up on pocket money. will try again one day when he understands better about money. probably in about 35 years if his father is anything to go by.
i think some kids just 'get' money(conceptually!). i can remember being 5 and saving and saving til i'd got enough coppers for a £1 note and being utterly thrilled. ds1 just loves spending money. and also wouldn't remotely be interested in a reward system, he didn't even want stickers on a chart when he was a toddler...
There was a 9 year old on supernanny the other night (I have no experience with this age yet!) and she got treats like getting out to play, or a girly day out for good behaviour/getting showered on her own etc. Maybe this might be better than money?
going out to play might be a good one actually. i just think that at 9 he is too old to have me standing over him to make sure that he's cleaned his teeth and needs some sort of incentive to make him play ball, so to speak.
nb if i try NOT standing over him, he tells barfaced lies and doesn't do it.
maybe something over then money? a magazine he reads? or friend over for dinner or something?
we have a little chart for our 3 year old, and thought she wouldnt really get it but she responds really well to it. its not a massive part in her life or anything but plays a part in bedtime, and eating dinner etc.. and if she gets all the stickers in a row she is rewarded with a trip to a park, or ride on her bike, baking, swimming.. things like that!?
