Using real-life examples from her ""Money Smart Kids"" column she has written for more than a decade, Bodnar offers creative cures for the grocery-cart ""gimmies,"" plus guidance on how to set up a simple allowance system that works, help kids learn the virtues of working for pay, and how to turn kids onto saving and investing.
