Last Updated on July 18, 2023

Many parents feel that providing their baby with a swing or bouncer can help make them more comfortable and promote better sleeping habits. However, there is concern among some medical professionals about the potential harm associated with the extended use of a baby swing for overnight sleep.

Pediatricians believe prolonged use of a baby swing can affect the development of the spine and lead to poor posture, scoliosis, and other issues

Therefore, parents should be aware of this potential risk when considering whether or not to use a baby swing for overnight sleep.

In this article, we will explore sleeping in a swing is bad for spine and why doctors are concerned. We will provide the scientific evidence that backs up their worries and look at potential ways to reduce or eliminate the risk. So, keep reading!

Is Baby Sleeping In Swing Bad For Spine?

Is baby sleeping in swing bad for spine?

Yes, a baby sleeping in a swing for a prolonged time can be bad for the spine. Studies have shown that extended use of a rocking baby chair or bed can cause pressure on the spine, leading to poor posture and abnormal growth patterns.

This is particularly true if the baby’s body is not properly supported when in the seat, as this will allow the head and neck to fall forward and put a strain on the spine.

Additionally, the rocking motion of the swing can cause a baby to twist its upper body, which can also lead to spinal issues.

In addition, some experts have found that babies sleeping in swings for extended periods of time may be at an increased risk for Sudden Infant Death Syndrome (SIDS).

“Babies in the swing should be monitored closely and not left alone for extended periods of time.”, says Dr. Gina Jansheski, a board-certified pediatrician with over 20 years of experience. “We recommend that babies are only placed in a swing or bouncer if they are supervised at all times.”

When we asked dr. Gina, how long can a baby be in a swing? She said, “Babies should never be in a swing or bouncer for more than 30 minutes at a time, and no more than 1 hour total per day.”

She even emphasized if the baby falls asleep in a swing, it’s important to take the baby out of the swing and place them in their crib.

It’s because the baby’s spine is still developing and needs to be supported on a flat surface with the neck in a neutral position.

On the other hand, most swings are upright and the baby’s head is likely to fall forward, blocking the baby’s airway and potentially leading to SIDS.

The American Academy of Pediatrics suggests laying the baby on their back on a flat, firm surface for all sleep times.

So, sleeping in a swing is not only bad for spine development but can also increase the risk of SIDS. That’s why we suggest limiting the use of a swing and only putting the baby in it when they’re awake and supervised.

Is it safe to allow baby to sleep in swing?

As stated above, the American Academy of Pediatrics does not recommend allowing babies to sleep in a swing for extended due to its potential risks. They suggest laying the baby on their back on a flat, firm surface for all sleep times.

The absence of a firm, flat surface may increase the risk of a baby rolling over and suffocating, leading to SIDS.

Additionally, the rocking motion can cause the infant’s spine to twist, potentially leading to spinal issues and poor posture over time.

Dr. Gina Jansheski also recommends being aware of the length of time a baby spends in the swing and never leaving an infant unattended in a swing.

What are the Risks of Putting Your Baby to Sleep in a Swing?

Several potential risks are associated with allowing a baby to sleep in a swing. These include:

Poor Posture & Spinal Abnormalities 

The rocking motion of the swing can cause the spine to twist, leading to misalignments and poor posture over time. Newborn’s neck and back muscles are still developing, so providing proper support and alignment for the spine is important.

Increased Risk of SIDS 

Keeping a baby in an upright position can block the airway and increase the risk of suffocation, creating a greater chance of SIDS. AAP advises parents to lay the baby on their back on a flat, firm surface for all sleep times.


Prolonged use of a swing can over stimulate your baby and affect his/her sleep patterns. This can lead to poor sleeping habits, which in turn can cause issues with mood, development, and behavior.

Stress on the Neck and Shoulders

When a baby is left in an upright swing for extended periods of time, it can cause stress to build up in their neck and shoulders. This can lead to chronic pain, difficulty sleeping, and poor posture.

Poor Weight Distribution

Too much pressure on any one area of the body from being in the same position for too long can cause poor weight distribution and interfere with proper development.

Reduced Movement

The rocking of a swing limits the baby’s ability to move around freely, which is essential for their physical and cognitive development.

Higher Risk of Choking

When babies are in an upright position, it increases the risk of choking because they are more likely to spit up or vomit. This can increase the risk of serious complications like aspiration pneumonia.

Increased Risk of Falls

Swings can be dangerous if a baby is not secured properly, as it increases the risk of falls and potential injury. It’s important to make sure your swing is secure before placing your baby in it.


Babies have a harder time regulating their body temperature, so the risk of overheating increases when they are in a swing. This can cause severe complications like dehydration and heat exhaustion. Make sure to check the temperature of your baby’s swing often and keep it comfortable for your little one.


Babies can become anxious when they feel like they are stuck in one position or unable to move freely. This may lead to fussiness, making it difficult for the baby to settle down and get a good night’s sleep.

Poor Playtime

Prolonged use of a swing limits the amount of time your baby has to play and explore their environment. This can interfere with their development and impede their ability to learn new skills.

Dr. Jansheski emphasizes Parents should be aware of the potential risks associated with using a swing as a sleeping aid for their babies. A flat surface, like a crib or bassinet, should always be used as the primary sleep area for babies and a swing should only be used as a supplement or for brief periods of time.

When using a swing, make sure to follow all safety guidelines and check on your baby periodically to ensure their comfort and safety.
