Should I allow my baby to sleep in their car seat?

While it is common for babies to fall asleep in a car seat during travel, it is generally not recommended for them to sleep in a car seat for extended periods, especially when the car seat is not in the car.

It is acceptable for babies to sleep in properly installed car seats while traveling. Car seats are designed to protect infants in the event of a collision and minimize risks during brief naps. However, these naps should be monitored, and the baby should not remain in the car seat for long durations.

What are the key considerations when it comes to baby sleeping in a car seat?

Here are some important safety considerations:

Angle of the Car Seat: In a car, car seats are usually installed at the proper angle to keep a baby’s airway open. If you’re using an infant seat, you likely needed to use a bubble level found on the car seat itself, or the car seat base when you installed it to ensure proper angle. However, when a car seat is placed on a flat surface outside the vehicle, the angle may change, increasing the risk of the baby’s head falling forward, which can obstruct their airway.

Duration: Extended periods in a car seat can also lead to positional asphyxiation, where a baby’s breathing is compromised because of their position. If their head falls forward and obstructs their airway, this risk is heightened because infants lack the neck strength to reposition themselves. Short naps during car rides are generally unavoidable and can be safe, but prolonged sleep in a stationary car seat is not advised.

Supervision: If a baby falls asleep in a car seat, it is crucial they remain under supervision. Check for their head positioning and make sure they are breathing comfortably.

Alternative Sleeping Arrangements: The American Academy of Pediatrics (AAP) advises moving babies to a firm, flat sleeping surface (such as a crib, or bassinet) as soon as possible after leaving the vehicle. Car seats are not designed for overnight sleep, or as a substitute for safe sleep environments. 

Overall, the safest recommendation is that while brief periods of sleep in a properly installed car seat are unavoidable during car rides, for regular sleep, babies should be placed on their backs on a flat and firm surface in a crib, bassinet, or play yard. Always follow the guidelines provided by the American Academy of Pediatrics (AAP) regarding safe sleep practices.
