Much of what your children learn about money is not from the conscious efforts you make to teach money management. Children are great imitators. Children pick up your values, attitudes, and money habits by watching and listening to you. In fact, you do not have to say anything to pass along money attitudes, habits, or decision-making style.
This website has some short helpful videos that demonstrate how to be a positive example and help your children learn to manage money early on. It is a gift that will last a lifetime! http://www.ecb.org/finance/parents/moneyhabits.html
