One more question...
I like the idea of having allowance tied to being a member of the family and not contingent on doing chores. Also, chores are expected on command in our household with our 3 year old twins. However, I am really interested in teaching them about money; earning, saving, compounding, giving, buying, etc., and how do you suggest approaching this with 3 year-olds. I want them to also learn the value of working for money, as that is something they'll have to do for a lot of years in the future.
