Overview
Why the Rear-Facing Position Matters
A young child is not simply a smaller adult. The head is proportionally larger, the neck is less developed, and the spine and supporting tissues are still maturing.
A young child is not simply a smaller adult. The head is proportionally larger, the neck is less developed, and the spine and supporting tissues are still maturing. In a frontal collision, the head moves forward forcefully. If the child is facing forward, the harness restrains the torso while the head and neck continue moving, placing substantial stress on the cervical spine. A rear-facing restraint changes how that force is distributed. The shell supports the back of the head, neck, and torso together, allowing the child to “ride down” the crash against the strongest, broadest surface of the restraint. This is why rear-facing is the safest position for infants and young toddlers—not merely a rule based on age. Every infant should use a rear-facing child restraint until the child exceeds that seat's manufacturer-stated height or weight limit. Most children are safest remaining rear-facing until at least age 2, and many current seats permit rear-facing use until approximately age 4. The label on the specific restraint, rather than a generic age chart, determines whether the child still fits.
