AAP Car Seat Safety Guidelines: Rear-Facing Until Age 2. 1  Although the new baseline is now age two, the AAP has advised parents since 2002 to keep kids rear-facing until they reach the height or weight limit of their car seat.
There are different types of rear-facing car seats. Infant-only seats can only be used rear-facing. Convertible and 3-in-1 car seats typically have higher height and weight limits for the rear-facing position, allowing you to keep your child rear-facing for a longer period of time. Ages 1 to 3 years. Keep your child rear-facing in a convertible or 3-in-1 car seat as long as possible.
