Car Seat Safety For Preemies

Premature infants are required to undergo a car seat test before being discharged from the hospital. This test is recommended by the American Academy of Pediatrics (AAP) for babies born before 37 weeks gestation, especially those with low birth weight or specific medical conditions. It involves monitoring the baby for any signs of bradycardia, apnea, or oxygen desaturation(1).

To ensure the best results during the test, here are some key guidelines to follow:


Securely fasten and buckle your child into the car seat, just as you would when driving them home. Ensure a snug fit and prevent the child from slouching, as this will provide more accurate readings for the doctors.


Wrap the baby snugly in a swaddle to keep them comfortable and promote uninterrupted sleep during the test.


Adjust the seat to its highest position, allowing the baby’s airways to remain unobstructed and ensuring continuous breathing. Use the level indicator to ensure proper recline.


Avoid conducting the test immediately after a feeding. Allow sufficient time for the baby to digest breast milk or formula to minimize the chances of reflux and vomiting.

How To Choose The Best Car Seat for Premature Babies?

Here are some specific factors to consider when searching for a car seat for a preemie:

Minimum weight requirements:

Convertible seats and certain infant bucket seats typically have a minimum weight requirement of 5 pounds. Since many preemies weigh less than this, it is advisable to find a seat with a lower weight requirement. Some infant bucket seats have a minimum weight requirement of 4 pounds, but caution should be exercised when selecting a car seat.

Body support for small babies (infant insert):

Most infant car seats come with an infant insert that provides additional support for newborns. These inserts may offer head support or full-body support. The added cushioning is crucial for comfort and helps prevent a baby’s chin from resting on their chest. Newborns lack head control and tend to slump forward in car seats, so a good infant insert positions the head slightly back from the chest to prevent slumping.

Lowest harness position:

When securing the car seat harness, the straps should be positioned as close to shoulder level as possible, or slightly below. A challenge when finding a properly fitting car seat for a preemie is that the lowest harness position on many seats is too high, resulting in the harness being above shoulder level rather than at or below it. While many infant bucket seats have a lowest harness level of around 6 inches, there are seats available with 5-inch harness levels, which are better suited for preemies.

Handle position:

The handle on an infant bucket seat is typically raised when carrying the car seat, but some car seats require the handle to be in the “down” position when the seat is in the vehicle. Moreover, certain car seats specify that when the handle is down, a specific amount of space must be maintained between the car seat and the front vehicle seat. This can be challenging in more compact cars, such as sedans.

Harness adjustability:

While it is increasingly common for car seats to have no-rethread harnesses, there are still models without this feature. As your child grows, the harness strap position needs to be adjusted to ensure the straps are at or slightly below shoulder level when rear-facing. A no-rethread harness allows for easy adjustment without the need to remove and rethread the harness straps through different slots.

Weight of the seat:

When dealing with an infant seat, the weight of the seat becomes an important consideration for portability. Infants often fall asleep in the car, and it can be disruptive to wake them up when removing them from the car seat. A lightweight seat that is easy to carry is beneficial for keeping your little one asleep. Any seat under 10 pounds is generally sufficient, but the lighter the seat, the easier it is to transport.


Car seats have an expiration date, typically ranging between 5 and 10 years. Although your baby won’t use an infant seat for that entire duration, if you plan to use it for multiple children, the expiration date becomes significant in terms of cost-saving measures.

Height and weight limits:

All car seats have both minimum and maximum weight limits. Larger ranges in these limits allow for extended use of the car seat. It is worth noting that most children outgrow the height category before the weight category, so be mindful of car seats that emphasize high weight limits.

Convertible Car Seat VS Infant Car Seat

Convertible seats typically require a minimum weight of 5 lbs. Many parents choose to start with a convertible seat because it offers a longer lifespan and better value for money.

One drawback of convertible seats is their weight, and they are not compatible with travel systems. On the other hand, infant seats are convenient for quickly installing and removing from the car. If your baby falls asleep during the car ride, you can simply take the entire seat with you without disturbing their sleep.

In general, it is easier to find infant car seats with lower weight limits, and they are generally more portable. That’s why the list of best car seats for preemies predominantly includes infant car seat styles.
