Is It OK for a Newborn to Sleep on the Side?

Is It OK for a Newborn to Sleep on the Side?

Peak Kuang |

As a new parent, one of the many things you'll worry about is your baby's sleep. Ensuring your little one is safe and comfortable during naps and nighttime is critical, and many wonder: Is it okay for a newborn to sleep on the side? 


While the idea might seem harmless or beneficial, health experts provide specific guidelines to keep newborns safe while sleeping.


Answering the Question: Is It OK for a Newborn to Sleep on the Side?

The short answer is no. Sleeping on the back is the safest option for newborns. According to leading health organizations such as the American Academy of Pediatrics (AAP), putting babies to sleep on their backs helps reduce the risk of sudden infant death syndrome (SIDS). 


This risk is higher when babies sleep on their stomachs or sides because they may roll into an unsafe position where breathing could be compromised.


For parents who wonder if is it ok for a newborn to sleep on the side, the safest approach is to place babies on their backs for all sleep sessions, including naps. Babies cannot roll over independently until they are older, so maintaining this position during sleep reduces the risk of dangerous situations.


Why Side Sleeping Can Be Risky for Newborns

There are clear reasons why side sleeping is not recommended for newborns. When babies sleep on their side, there's a higher chance they may roll onto their stomachs and not be able to roll back. Stomach sleeping can lead to difficulty breathing and an increased risk of SIDS.

Although it might seem like side sleeping could help babies with specific issues, such as reflux, the risks outweigh the perceived benefits. Instead of side sleeping, it is best to place your baby on a firm mattress that supports their body and promotes airflow.


Creating a Safe Sleep Environment

Beyond sleep positioning, several ways exist to create a safe sleep environment for your newborn. Here are some critical practices to follow:

  • Use a firm mattress: A firm mattress helps maintain a flat sleep surface, critical for reducing the risk of suffocation or other breathing difficulties. The futon mattresses from Zonli Home are a good choice. They feature a 100% cotton cover for breathability and skin-friendly comfort. The hollow fiber filling provides soft cushioning, and the memory foam offers support, helping your baby sleep while promoting proper posture. 
  • Keep the crib free of loose items: Pillows, blankets, and stuffed animals should be kept out of the crib to reduce the risk of suffocation.
  • Room-sharing: It’s recommended that babies sleep in the same room as their parents, but in their own crib or bassinet, for the first six months.

What to Do If Your Baby Rolls Onto Their Side?

Some parents may notice their baby rolls onto their side during sleep, even if they were initially placed on their back. If this happens, gently reposition your baby onto their back. This should continue until your baby is old enough to roll both ways—back and front to back—on their own.

When babies reach 4 to 6 months of age, they typically develop enough strength and motor skills to change positions while sleeping. At this point, the question of “Is it ok for a newborn to sleep on the side?” becomes less of a concern, as they can move freely and find comfortable positions on their own.


Concerns About Reflux and Flat Head Syndrome

Many parents worry about specific issues, such as reflux or flat head syndrome, and how they relate to sleep positioning. Let’s address these concerns:

  • Reflux: For parents who wonder if side sleeping might help reduce reflux, it’s essential to stick to back sleeping, as it remains the safest option. If your baby has significant reflux, consult your pediatrician for other methods to manage it safely without compromising sleep positioning.
  • Flat Head Syndrome: When babies sleep on their backs, some parents notice flat spots developing on their heads. This condition, known as plagiocephaly, can be managed by providing plenty of tummy time during the day and varying your baby’s head position during sleep.

Tummy Time and Its Role in Sleep Safety

Tummy time is an important activity that can help develop your baby’s neck and shoulder muscles while reducing the risk of flat head syndrome. Supervised tummy time during the day allows babies to strengthen their muscles, which will help them roll over on their own as they grow.

As babies can roll over independently, the concern about whether their side is okay diminishes. It is not possible for a newborn to sleep on the side since they can move into different positions during sleep.


When Side Sleeping Becomes Safe for Babies

Once babies can roll over from back to stomach and stomach to back on their own, side sleeping becomes less risky. This usually happens between 4 and 6 months of age. 

However, starting each sleep session is essential by placing your baby on their back. Once they can roll independently, they will likely adjust their sleep position to what feels most comfortable.

During this stage, babies develop the necessary strength and motor control to move freely during sleep, making it less concerning if they roll onto their side. However, it’s still a good idea to monitor your baby’s sleep habits and consult your pediatrician if you have any concerns.


The Final Verdict: Is It OK for a Newborn to Sleep on the Side?

In conclusion, is it ok for a newborn to sleep on the side? The answer is no for newborns who cannot yet roll over on their own. The safest sleep position for your newborn is on their back, as this significantly reduces the risk of SIDS and other sleep-related dangers. 

As your baby grows and develops the ability to roll over independently, side sleeping becomes less of a concern.

By following safe sleep guidelines, choosing a supportive mattress, and addressing concerns like reflux or flat head syndrome, you can create a comfortable and secure environment for your baby. 

Always start by placing your baby on their back, and as they grow, trust that they will adjust to a safe position during sleep.
