Once children outgrow their booster seat (usually at 10 â 12 years old) they can use the adult lap/shoulder safety belt if it fits them properly. Lap portion low over the hips/tops of thighs and shoulder belt crosses the center of the shoulder and center of the chest.
A parent has a 2-year-old in the clinic for a well-child checkup. We stopped using the car seat now that my child is older.. A car seat should be used until the child weighs 40 pounds, at approximately 4 years of age. After that point, a booster seat that complies with federal safety guidelines should be used.
