In a regular rear-facing car seat, babies sit semi-reclined. For some small, premature, or medically fragile babies, this position can cause the head to fall forward. That could block the baby's airway and make it harder to breathe. It can also lead to drops in oxygen levels or to pauses in breathing (apnea) or a slow heart rate (bradycardia).
Lying flat helps keep the airway open and makes breathing easier. Your baby's care team may suggest a car bed if:
- Your baby was born premature or at a low birth weight.
- Your baby did not pass the car seat test.
- Your baby has low muscle tone. This can make it hard to keep the head and airway in a safe position in a car seat.
- Your baby has a breathing or airway condition. For example, your baby may need to use extra oxygen or may have a tracheostomy.
- Your baby has a condition that requires them to stay flat, such as with some spinal problems.
