• When forward-facing, children should use the built-
in harness system for as long as possible until they
reach the maximum forward-facing weight or height
for their car seat. At that point, children should
ride in a belt-positioning booster seat. A booster
is no longer needed once the vehicle seat belt fits
properly, typically when they reach 4 feet 9 inches
(145 cm) tall and are between ages 8-12. Be sure
to check your local and state laws, as well as AAP
and NHTSA recommendations, for car seat usage.
