Many of the behaviors you like or dislike in your child directly reflect what you value. For example, there's really nothing wrong with your children eating with their fingers, if their fingers are clean. Whether children should use fingers or fork is dictated by values. Other areas of behavior that reflect values might include the following:
You cannot dictate what your children will ultimately hold. But if you want them to respect your values, be sure they are reasonable, that you establish them early, and that you consistently maintain them through instruction and example.
To teach by example, you must consistently live by your values. You cannot have one set of values that you try to impose on your children while you live by another.
Children follow good examples as well as bad. So take heart, parents. Continue being the kind of example you know Christ would want you to be. And don't be surprised when your values rub off on your children.
