The American Academy of Pediatrics (AAP) recommends that all infants ride rear-facing starting with their first ride home from the hospital. All infants and toddlers should ride in a rear-facing seat until they are at least 2 years of age or, preferably, until they reach the highest weight or height allowed by their car safety seat manufacturer. When infants outgrow their rear-facing–only seat, a convertible seat installed rear facing is needed.
All parents can benefit from getting installation help from a CPST to ensure that their seat is properly installed.
Types of Rear-Facing Seats:
Three types of rear-facing seats are available: rear-facing–only, convertible, and 3-in-1. When children reach the highest weight or length allowed by the manufacturer of their rear-facing–only seat, they should continue to ride rear-facing in a convertible or 3-in-1 seat.
Rear-facing–only seats
- Are used for infants up to 22 to 40 pounds, depending on the model.
- Are small and have carrying handles.
- Usually, come with a base that can be left in the car. The seat clicks into and out of the base so you don't have to install it each time you use it. Parents can buy more than one base for additional vehicles.
- Should be used only for travel (not sleeping, feeding, or any other use outside the vehicle).
Convertible seats (used rear facing)
- Can be used rear facing and, later, "converted" to forward facing for older children when they outgrow either the weight limit or the length limit, for rear facing. This means the seat can be used longer by your child.
- They are bulkier than infant seats, however, and they do not come with carrying handles or separate bases and are designed to stay in the car.
- Many have higher limits in rear-facing weight (up to 40–50 pounds) and height than rear-facing–only seats, which make them ideal for bigger babies and toddlers.
- Have a 5-point harness that attaches at the shoulders, at the hips, and between the legs.
- Should be used only for travel (not sleeping, feeding, or any other use outside the vehicle).
3-in-1 seats (used rear facing)
- Can be used rear facing, forward facing, or as a belt-positioning booster. This means the seat may be used longer by your child as your child grows.
- Are often bigger in size, so it is important to check that they fit in the vehicle while rear facing.
- Do not have the convenience of a carrying handle or separate base; however, they may have higher limits in rear-facing weight (up to 40–50 pounds) and height than rear-facing–only seats, which make them ideal for bigger babies and toddlers.
Installation Tips for Rear-Facing Seats:
Always read the vehicle owner's manual and the car seat manual before installing the seat.
When using a rear-facing seat, keep the following tips in mind:
- Place the harnesses in your rear-facing seat in slots that are at or below your child's shoulders. Ensure that the harness is snug (you cannot pinch any slack between your fingers when testing the harness straps over the child's shoulders) and that the harness chest clip is placed at the center of the chest, even with your child's armpits.
- Make sure the car safety seat is installed tightly in the vehicle with either LATCH or a locked seat belt. If you can move the seat at the belt path more than an inch side to side or front to back, it's not tight enough.
- Never place a rear-facing seat in the front seat of a vehicle that has an active front passenger airbag. If the airbag inflates, it will hit the back of the car safety seat, right where your child's head is, and could cause serious injury or death.
- If you are using a convertible or 3-in-1 seat in the rear-facing position, make sure the seat belt or lower anchor webbing is routed through the correct belt path. Check the instructions that came with the car safety seat to be sure.
- Make sure the seat is at the correct angle so your child's head does not flop forward. Check the instructions to find out the correct angle for your seat and how to adjust the angle if needed. All rear-facing seats have built-in angle indicators or adjusters.
- Check the car safety seat instructions and vehicle owner's manual about whether the car safety seat may contact the back of the vehicle seat in front of it.
- Still having trouble? Check with a certified CPST in your area who can help. See the end of this article for information on how to locate a CPST.
How to Install A Rear-Facing Car Seat - Video:
In this video, Benjamin Hoffman, MD, FAAP, a pediatrician and certified car seat technician, guides parents on how to properly install a rear-facing car seat. All infants and toddlers should ride in a rear-facing car seat until they are at least 2 years of age or until they reach the highest weight or height allowed by their car seat's manufacturer.
Common Questions about Rear-Facing Seats:
What if my baby's feet touch the back of the vehicle seat?
What do I do if my baby slouches down or to the side in the car seat?
Why should I dress my baby in thinner layers of clothing before strapping him or her into a car seat?
Bulky clothing, including winter coats and snowsuits, can compress in a crash and leave the straps too loose to restrain your child, leading to increased risk of injury. Ideally, dress your baby in thinner layers and wrap a coat or blanket around your baby over the buckled harness straps if needed.
