If so how much and what age?
I used to give my 5 yr old 10p a week (i know, but the idea was that if he kept his room tidy on friday after school he could buy a couple of penny sweets)
the idea was to show him you have to work for things, give him some responcibility and also to get his used to doing jobs.
Do you give your children pocket money? do they have to do anything for it?
