Parents of little ones in car seats, there’s a new rule you need to know about.

The American Academy of Pediatrics now says children should stay in rear-facing car seats until they hit the height or weight limit for the seat.

For most car seat manufacturers, that’s 40 pounds.

This new guidance tweaks what we were previously told that kids should ride rear-facing until age two.

Using the car seat correctly reduces the risk of death or injury by more than 70 percent.

All children younger than 13 years should be in a vehicle’s back seat.
