Clark and his wife have had some serious discussions about their middle child and her booster seat in the car. Their daughter was upset because at the age of 5 she was still using one while all her friends being dropped off at school were not.

The booster seat issue is one that's really been taken up by the states. Nearly 20 states have instituted new rules about the age that children have to stay in their boosters after they get out of the infant car seat. Maryland, Massachusetts and Michigan are among those with laws going on the books this summer.

Many states require children to remain in them up to their 8th birthday, or until they meet certain height and weight requirements -- usually 57 inches and 65 pounds.

Seatbelt design is such that a child may be killed or seriously injured in an accident that wouldn't greatly harm someone taller and heavier. In a panic stop, the shoulder part of a belt would hit a child directly across the neck. Enough said.

Is Clark trying to guilt you about booster seats? No, you have to make a decision for yourself. There's a certain expectation that childhood comes with a lot of bumps and bruises, but what we're talking about here is much worse than a bump or a bruise.
