Why does my baby have to have a "car seat test" before going home?

The car seat test (also called a car seat tolerance screen or car seat challenge) is a safety check often done before a newborn—especially a preterm or low-birth-weight baby—goes home from the hospital.

Here’s what it involves:

Purpose

• Newborns, particularly preterm infants, can have trouble keeping their airway open and maintaining normal breathing, oxygen levels, and heart rate when sitting semi-upright in a car seat.

• The test helps ensure your baby can travel safely in a car seat without issues like apnea (pauses in breathing), bradycardia (low heart rate), or oxygen desaturation.

When it’s done

• Usually for babies born before 37 weeks gestation.

• Also sometimes for low-birth-weight infants or those with certain medical conditions (e.g., airway problems, low muscle tone, heart or lung conditions).

How it works

1. Your baby is placed in the car seat you’ll use at home.

2. The seat is positioned at the correct angle, just like it would be in your car.

3. Your baby is strapped in securely.

4. A monitor tracks their breathing, heart rate, and oxygen levels for about 90–120 minutes (or as long as a typical car ride home).

5. Medical staff watch for any drops in oxygen, slowed heart rate, or breathing pauses.

Outcomes

• Pass: Baby maintains stable breathing, heart rate, and oxygen throughout the test. Safe to use the seat for travel.

• Fail: If baby has trouble, the care team may:

  • Re-test after a little more growth/maturity

  • Suggest a car bed (special restraint system that lets baby lie flat while riding)

  • Delay discharge until the baby is ready
