We want to start teaching DD about tithing and the value of money as quickly as we can. She is currently 17 months old. The idea is to get her three different piggy banks - one labeled for her, one for savings, and one for tithing. We will give her 10 dimes each week and have her put 8 in her bank, 1 in savings (10%), and one in tithing (10%).

Anyone do something similar? At what age did you start?
