How Long Should You Keep Your Child Rear-Facing in a Car Seat?

Get the answer along with tips for safe installation

As a parent, you celebrate each milestone your child achieves — sitting up, crawling, taking first steps and saying their first word. But graduating to a front-facing car seat? That’s one such milestone that shouldn’t be rushed, according to guidelines from the American Academy of Pediatrics (AAP).

For years, parents have learned that keeping their child rear-facing in a car seat until age 2 is the best practice. But that recommendation has since been updated and now suggests that parents keep their children in rear-facing seats for as long as possible.

Purva Grover, MD, Director of Cleveland Clinic Children’s Pediatric Emergency Departments, says a child in a rear-facing seat has less risk for serious (or fatal) injury if involved in a crash.

“Because of the way their head and neck is positioned, when there is a big car crash involving a massive force — if they were to be front-facing, the positioning of the head and neck would give them bad whiplash, and with small children, it could actually cause much more damage,” Dr. Grover explains.

Types of rear-facing seats

There are a few options when it comes to rear-facing seats.

All-in-one seats

As the name implies, all-in-one seats have multiple uses. They can be used as a booster seat, a rear-facing seat or a forward-facing seat. However, they should only be used for car rides. All-in-one seats don’t have handles or bases. They’re also much larger in size and have higher weight and height limits than other styles of rear-facing seats. If you decide to buy an all-in-one car seat, make sure it’ll fit in your car when it’s rear-facing as it’s a bigger seat.

Convertible seats

With these seats, you can start off using them as rear-facing and then transition to forward-facing when your child outgrows the weight and height limits for rear-facing seats. Convertible seats tend to be larger than rear-facing seats and they don’t have carrying handles or bases. They also tend to have a five-point harness that attaches between the legs and at the hips and shoulders.

Rear-facing only seats

These seats are small and can carry infants between 22 and 35 pounds or 26 and 35 inches. Rear-facing only seats tend to have a base that stays in the car. However, rear-facing seats should only be used for travel and not for sleep or feeding times.


Rear-facing car seat guidelines for installation

Here are a few things to keep in mind when placing a rear-facing car seat in your vehicle.

Make sure the harness is in the right place

The car seat harness should be at or below your little one’s shoulders. Once situated, it should be snug. The harness’ chest clip should be in the middle of your child’s chest and lined up with their armpits.

Don’t place the seat in front of an active airbag

If the airbag for the front passenger’s seat is active, don’t put a rear-facing car seat there. Doing this could lead to serious injuries or even death. The reason being is if the airbag inflates, it’ll knock the car seat into your child’s head or worse.

Make sure the seatbelt is attached correctly

For rear-facing convertible or all-in-one seats, make sure the seat belt or lower anchor webbing is in the correct belt path. If you’re not sure, review the instructions.

Check the car seat’s angle after installation

To ensure that your child’s head doesn’t flop around, refer to the manual for the right seat angle. Once you find it, adjust the seat as needed.

If you need help with car seat installation, a Child Passenger Safety Technician (CPST) can make sure that it’s properly secured and ready for use.

When can you turn the car seat forward?

According to the AAP and the National Highway Traffic Safety Administration (NHTSA), children up to 3 years old should stay in a rear-facing car seat until they reach the top height or weight limit suggested by the car seat’s manufacturer. When your child hits one of these limits, they can ride in a forward-facing car seat with a harness and tether.


The best way to protect your child

According to the Centers for Disease Control and Prevention (CDC), car accidents are a leading cause of death for children in the U.S. In 2019, more than 600 children age 12 and younger died in motor vehicle crashes, and more than 91,000 were injured.

However, the CDC also states that car seat use reduces the risk for injury in crashes by 71% to 82% for children, when compared with seat belt use alone.

The updated recommendations also say that once a car seat has been turned around, it should remain forward-facing until your child reaches the seat’s weight and length limits. Then, your child should start using a booster seat. Children who exceed booster seat limits should use a lap and shoulder seat belt in the back seat of the car until they’re 13 years old.

Convenience shouldn’t come before safety

Dr. Grover agrees with the recommendations and says that when it comes to minimizing injury risk, safety should always come before convenience. She adds that it’s important for pediatricians to talk to parents about the guidelines and explain why they’re in place. The complete recommendation is available through the American Academy of Pediatrics.
