The American Academy of Pediatrics said today that children should be seated in rear-facing car seats until they are two years old.

The new advice given by the Pediatrics group contradicts their prior recommendations that babies should ride facing the rear of the car until they reach their first birthday or are 20 pounds.

But a study they conducted in 2007 showed that children up to 24 months are more likely to be hurt in a crash if seated in a front-facing car seat.

The AAP says that parents should have their children rising in booster seats until they are about 4’9” tall and should ride in the back seat until they are 13 years old, reported the Wall Street Journal.
