At what weight should infants transition from a rear-facing car seat?

The appropriate transition weight for infants from a rear-facing car seat is generally around 20 pounds (9.1 kg). This weight corresponds with car seat manufacturers’ recommendations and safety guidelines established by organizations such as the American Academy of Pediatrics.

Most convertible car seats allow children to remain in rear-facing mode until at least this weight limit is reached, although many seats have higher weight limits. Keeping an infant rear-facing is the safest position for them during car travel since it provides better support for the head, neck, and spine in the event of a collision.

While some seats may allow infants to transition at lower weights, 20 pounds is widely agreed upon as a standard threshold that supports optimal safety during travel. After reaching this weight or when the top of the child's head is within one inch of the top of the car seat, parents and caregivers are advised to consider transitioning to a forward-facing seat.
