Even with the most meticulous prenatal care, some infants may arrive earlier than expected. In such cases, hospitals prioritize the safe transportation of these newborns. Often, babies born before 37 weeks gestation, or those with specific medical conditions, require a car seat tolerance test, also known as a car seat test, to assess their ability to travel safely in a standard car seat. For some infants, particularly those with breathing or heart rate concerns when semi-reclined, a traditional car seat might not be suitable. This is where Car Beds become a crucial alternative, ensuring the safest possible journey for these vulnerable little ones.
What is a Car Bed?
A car bed is a specialized restraint system designed for infants who cannot safely travel in a semi-reclined position, like that of a standard rear-facing car seat. Unlike car seats which secure a baby in a seated or reclined position, car beds allow infants to lie flat on their backs while traveling in a vehicle. This horizontal positioning is medically necessary for certain babies, primarily due to respiratory or cardiac concerns. They resemble a small bassinet and are specifically designed and crash-tested for vehicle use, providing a safe and secure environment for infants during car journeys.
Why are Car Beds Necessary?
Medical professionals may prescribe a car bed if a newborn exhibits difficulties maintaining stable breathing or heart rate when placed in a semi-reclined car seat. This is often identified through the car seat test, where a nurse monitors the baby’s vital signs while they are positioned in a car seat for a specified period. The American Academy of Pediatrics (AAP) provides guidelines recommending monitoring for infants who fall into the following categories before their first car ride:
- Premature Infants: Babies born before 37 weeks of gestational age are often at higher risk.
- Position Intolerance: Infants of any age who cannot tolerate a semi-reclined position, such as in a rear-facing car seat, due to breathing difficulties or other medical conditions.
- Risk of Apnea or Bradycardia: Infants at risk for apnea (pauses in breathing), bradycardia (slow heart rate), oxygen desaturation (low oxygen levels), or obstructive apnea (blocked airway), such as those with Pierre Robin Sequence or other conditions affecting airway management.
If a baby fails the car seat test or exhibits risk factors, a pediatrician may recommend a car bed to ensure safe transportation. In some cases, a home monitor to track heart rate and breathing may also be prescribed alongside the car bed.
Car Bed Safety: Essential Guidelines
Using a car bed safely is paramount to protect your infant. Always adhere to the car bed manufacturer’s instructions meticulously, alongside these crucial safety guidelines:
- Rear Seat Placement: The car bed must always be installed in the rear seat of the vehicle. Position it so the baby’s head is towards the center of the car, away from the side door. This minimizes potential impact in case of a side collision.
- Secure Installation: Utilize the vehicle’s seat belt to firmly secure the car bed to the car. Ensure the seat belt is tightly fastened according to the manufacturer’s directions to prevent any movement of the car bed during travel.
- Supine Positioning: Unless explicitly instructed otherwise by your pediatrician, always place your baby on their back in the car bed. While some specific medical conditions might rarely warrant prone (on the abdomen) positioning, this should only be done under strict medical guidance and the pediatrician will indicate when supine positioning becomes safe.
- Equipment Security: If your baby requires a breathing monitor or other medical equipment during car rides, learn the proper way to secure this equipment. This prevents it from becoming a projectile in the event of a sudden stop or accident.
- Constant Supervision: While the car is moving, a responsible adult other than the driver should always be in the back seat to observe the baby closely and ensure their wellbeing throughout the journey.
- Limit Travel Time: Minimize car journeys, especially extended trips, until your baby is deemed medically stable enough to transition to a standard car seat. For trips exceeding three hours, plan for stops every two to three hours. These breaks allow you to take your baby out of the car bed for feeding, diaper changes, and general care, promoting comfort and circulation.
- Avoid Other Restraints: Refrain from using baby seats, bouncy chairs, baby swings, backpack carriers, and infant carriers until your baby has been re-tested and cleared for semi-reclined positioning by their pediatrician. These devices place infants in similar semi-reclined positions to car seats and may pose the same risks for babies who require car beds.
If you encounter any uncertainties regarding the correct installation or usage of your car bed, seek assistance from certified Child Passenger Safety Technicians (CPSTs). Resources like local car seat fitting stations can provide invaluable hands-on guidance to ensure your baby’s car bed is installed and used correctly.
Transitioning to a Traditional Child Safety Seat
As your baby grows and their medical condition improves, they will likely transition from a car bed to a traditional child safety seat. This transition is typically guided by your pediatrician, who will reassess your baby’s breathing and heart rate stability in a semi-reclined position. A repeat car seat test may be conducted to determine if your baby is now medically stable enough for a standard car seat.
Once your pediatrician gives the go-ahead for a car seat, it’s crucial to choose and use it correctly.
Tips for Using a Traditional Child Safety Seat Safely
When your baby is ready for a traditional car seat, prioritize safety with these essential tips:
- Weight and Height Limits: Always verify the car seat’s weight and height limits before use and ensure your baby meets these requirements. Using a seat prematurely or beyond its limits compromises safety.
- Infant-Specific or Convertible Seats: For newborns and young infants, infant-only car seats or convertible car seats with a five-point harness system are recommended. These offer optimal comfort and positioning for smaller babies.
- Harness System is Key: Ensure the car seat you choose has either a three- or five-point harness system. Avoid car seats with shields, abdominal pads, or armrests, as these can pose breathing risks for infants or cause injury in a crash.
- Use Only Approved Head Supports: Only use head supports that are specifically included with the car seat by the manufacturer. Never use aftermarket head supports, as they may not be crash-tested with the seat and can interfere with safety. For smaller babies needing extra support, rolled blankets placed alongside the baby can provide safe head and body support as shown below.
- Crotch Strap Position: Select a car seat with the shortest possible distance between the crotch strap and the seat back. This minimizes the risk of the baby sliding down and out from under the harness.

Correct Car Seat Positioning
Proper positioning is just as vital as choosing the right car seat:
- Buttocks and Back Placement: Ensure your baby’s buttocks and back are firmly against the back of the car seat.
- Harness Snugness and Position: The harness should be snug, lying flat and remaining at or slightly below your baby’s shoulders when rear-facing.
- Retainer Clip Location: Position the retainer clip at armpit level, in the center of your baby’s chest. Never place it over the abdomen or near the neck.
- Extended Rear-Facing: Keep your infant in a rear-facing car seat for as long as possible, until they reach the maximum weight or height limit specified by the car seat manufacturer. Many convertible seats allow rear-facing use for two years or more, which is the safest position for young children.
- Proper Recline Angle: Recline the rear-facing car seat according to the manufacturer’s instructions. Most seats have built-in indicators to help you achieve the correct angle. If needed and permitted by the manufacturer, a tightly rolled blanket or pool noodle can be placed under the base of the car seat to achieve the correct recline.
- Rear Seat Only for Rear-Facing: Never install a rear-facing car seat in the front passenger seat, especially in vehicles with active airbags.
- Rear Seat Supervision: Whenever possible, have another adult sit in the back seat with the baby to monitor them during travel.
For assistance with car seat installation, utilize community child safety seat inspection stations. These stations offer expert help to ensure your car seat is correctly installed, maximizing your child’s safety.
Additional Medical Equipment Considerations
If your baby is discharged with a medical monitor, remember these crucial points for car travel:
- Sufficient Battery Power: Ensure you have ample battery power for the monitor, at least double the anticipated duration of your car journey.
- Secure Medical Equipment: Properly secure any portable medical equipment in the car to prevent it from becoming a hazard in the event of sudden braking or a collision.
Prioritizing your infant’s safety during car travel is paramount, especially for medically fragile newborns. Understanding the role of car beds and adhering to safety guidelines for both car beds and traditional car seats empowers parents and caregivers to make informed decisions and ensure the safest possible journeys for their little ones.
