For most parents, the decision point for transitioning a child out of a booster and into a seat belt comes when a child grows to 4 feet 9 inches tall, usually between the ages of 8 and 12.
The transition to a seat belt provides an opportunity you to teach your child about safety. The first message is simple: If your child is a "Tween," (between the age of 8 and 12), the safest place for them to ride in the car is in the back seat - buckled up.
As a parent, you influence your kid by modeling safe driving practices - including buckling up every time you get in the car. Teach your tween that family safety is the responsibility of passengers as well as the driver.
