Parents ready to let their tot look toward the dashboard may think twice about the car seat installation. A new study out in the British Medical Journal suggests parents should keep their children in rear facing car seats until age four.

Most mothers and fathers follow the guidelines set by the American Academy of Pediatrics — that wee ones stay in rear-facing seats until age one and surpass 20 pounds. Some folks choose to turn them around earlier for fear of crushing their lil one's limbs. According to Dr. Joseph O'Neil:

A child is 5.53 times safer during their second year of life in a rear-facing car seat versus a forward-facing one.

The video certainly has me questioning my daughter's car seat position, but I don't see any older children still sitting backward. Maybe that's because the child's knees would be next to his ears. How old are your kiddos and which way do their seats face?
