Ask your five-year old where money comes from, and the answer you'll probably get is "From a machine!" Even though children don't always understand where money really comes from, they realize at a young age that they can use it to buy the things they want. So as soon as your child becomes interested in money, start teaching him or her how to handle it wisely. The simple lessons you teach today will give your child a solid foundation for making a lifetime of financial decisions.
