Yes, a newborn can and absolutely must sit in a car seat, but it must be a rear-facing infant car seat installed correctly. The American Academy of Pediatrics (AAP) and the National Highway Traffic Safety Administration (NHTSA) are clear on this: the first car ride home from the hospital requires a properly sized rear-facing seat. The primary concern for newborns is their underdeveloped neck and spine, which cannot support the heavy weight of their head. A rear-facing seat cradles the baby's entire back, head, and neck, distributing the forces of a crash across the shell of the car seat, not the baby's fragile body. This is the single safest way for an infant to travel.
The key is choosing the right seat and using it properly. You need a seat specifically designed for infants, typically one with a 5-point harness (with straps over the shoulders and hips, and between the legs) and a carrying handle. These seats are often part of a "travel system" but are essential for vehicle safety. The harness must be snug against the baby's body; you should not be able to pinch any excess strap material at the child's shoulder. The chest clip should be positioned at armpit level.
Correct installation is non-negotiable. Most parents use either the vehicle's seat belt or the LATCH system (Lower Anchors and Tethers for Children) to secure the base. Whichever method you choose, the car seat base should not move more than one inch side-to-side or front-to-back at the belt path. It’s highly recommended to have your installation checked by a Child Passenger Safety Technician (CPST). You can find a free inspection station near you via the NHTSA website.
Additionally, parents must be cautious about the baby's position in the seat. Ensure the baby's back is flat against the seat, and the harness is at or below the baby's shoulders. To prevent slouching and potential breathing difficulties, carefully roll small receiving blankets and place them on either side of the baby, never behind the back or under the harness. Most importantly, car seat safety means the car seat is for travel only; it is not a safe place for a baby to sleep unattended outside the vehicle.
