How long should my baby ride rear-facing?

The AAP recommends that children remain rear-facing as long as possible, until they reach the highest weight or height allowed by their car seat. That limit is printed on the seat label and in the manual, and many convertible seats allow rear-facing well past a second birthday. Turning forward depends on the seat limits, not on a birthday.

Is a more expensive car seat safer?

No. Every car seat sold in the United States must meet federal safety standards, and NHTSA is clear that the best seat is the one that fits your child, fits your vehicle, and gets used correctly on every ride. A higher price buys convenience and fabric, not more crash protection.

Where can I get my car seat installation checked for free?

Certified child passenger safety technicians check seats for free. Use the NHTSA online locator for car seat inspection stations, or ask at your local fire station or health department, since many host certified technicians or seat check events.

Is it safe to use a secondhand car seat?

Only if you know its full history. The seat must never have been in a moderate or severe crash, must not be expired or recalled, and must have all of its parts and labels plus the manual. If you cannot confirm those things, choose a new seat, since every new seat that meets federal standards is a safe choice.

Newborn car seat basics: the ride home and the first year

June 10, 2026 · 8 min read

The ride home from the hospital is the first trip your baby ever takes, and the car seat is the one piece of baby gear that is truly about safety. The good news is that you do not need the most expensive seat on the shelf. You need a seat that meets federal safety standards, fits your car, and is used correctly on every ride. This guide covers the basics from the first day through the first year, based on guidance from the American Academy of Pediatrics (AAP) and the National Highway Traffic Safety Administration (NHTSA).

Rear-facing from day one

Your baby should ride rear-facing starting with the very first trip. The AAP recommends that children stay rear-facing as long as possible, until they reach the highest weight or height allowed by their seat, and NHTSA gives the same advice. A rear-facing seat cradles the head, neck, and spine in a crash, which is exactly what a new baby needs, because the head of a young baby is large and heavy compared to the rest of the body. A rear-facing seat always goes in the back seat, and never in front of an active airbag.

The hospital will expect a car seat at discharge

Plan to have your seat ready weeks before your due date, because most hospitals expect to see one before they discharge a newborn, and staff often watch you place the baby in it. Practicing ahead of time with the carrier, the harness, and the buckles makes that day far less stressful. If your baby is born preterm, the AAP recommends a car seat tolerance screening before discharge, a short period of observation in the seat to make sure your baby can breathe well in a semi-reclined position. Your care team will tell you if your baby needs one.

Choosing a seat: expensive does not mean safer

Every car seat sold in the United States must meet the same federal safety standards, so per NHTSA, any seat is a safe seat when it fits your child, fits your vehicle, and is used correctly on every ride. A higher price buys convenience features and fabrics, not more protection. For a newborn you can choose an infant-only seat with a carrier handle, or a convertible seat that starts rear-facing and grows with your child. Check the label for the weight and height range, and if you can, try the seat in your actual car before the birth.

Installing it correctly

The seat goes in the back seat, rear-facing, installed with either the lower anchors or the seat belt, following both your car seat manual and your vehicle manual, and not both systems at once unless the manufacturer allows it. Newborns need a semi-reclined angle so the head does not slump forward, and most seats have a built-in recline indicator to help you get it right. Once installed, the seat should not move more than an inch side to side or front to back at the belt path. For the harness, the straps lie flat at or below the shoulders while rear-facing, the chest clip sits level with the armpits, and the straps pass the pinch test: if you can pinch a fold of webbing at the shoulder, tighten the harness until you cannot.

Skip aftermarket add-ons, and register your seat

Head supports, strap covers, and padded inserts that did not come in the box were not crash tested with your seat, and NHTSA advises against products that were not made by the manufacturer for that model. If your newborn looks small in the seat, check the manual first, because many seats include their own newborn insert and instructions for small babies. Also take two minutes to register your seat, using the card that comes in the box or online, so you receive a direct notice if the seat is ever recalled. NHTSA also lists car seat recalls on its website.

Get the installation checked for free

You do not have to figure this out alone. Certified child passenger safety technicians check installations for free, show you how to harness your baby, and answer questions without judgment. NHTSA has an online locator for car seat inspection stations, and many fire stations, police departments, and health departments host certified technicians or seat check events. A short visit before your due date is one of the most valuable errands of late pregnancy.

Used seats, expiration dates, and winter coats

A used seat can be safe, but only when you know its full history. Skip any seat that has been in a moderate or severe crash, is past the expiration date printed on the label or in the manual, is missing parts or labels, or has an open recall. With a borrowed seat from a relative or friend, ask directly about crashes before you accept it. And in cold weather, remember that a bulky coat compresses in a crash and can leave the harness dangerously loose. Dress your baby in thin layers, buckle the harness snug, and put a blanket or the coat over the harness, never under it.

The first year, one ride at a time

Car seat questions keep coming during the first year: when to move the harness straps up, what to do when your baby reaches the seat limits, how to switch to a convertible seat. Materna is a bilingual, voice-first platform for pregnancy and postpartum care in Arizona, California, Texas, and Pennsylvania, and the Mommy Passport, free for patients, lets you save questions like these just by talking, in English or Spanish, so you can bring them to your pediatric visits. Materna does not replace your clinician, and for any urgent concern about your baby, call your provider, or 911 in an emergency.
