What we are going to do with our son is have him do chores and him get an allowance for it but he only gets it at the end of the month when family time is spent together. I think I would start at the age of 9-10.

    We never really gave an allowance... our children get what they need and really have no need for pocket money. They are allowed to use birthday money for anything special they may want .
