Essentials
Navigating newborn sleep sometimes feels like it needs a degree in logistics and wizardry - neither of which are available to new parents. One of the common questions parents face is can my newborn sleep on their side or tummy if they seem more comfortable there. The truth is, the safest sleep position for a baby is sleeping on their back on a firm flat surface but let’s explore in more detail why it’s so important and what else to consider while you wait for that degree in wizardy to come in the post.

Safe Sleep For Newborns

It goes without saying that keeping our babies safe is what is on most of our minds 24/7. Sleep in particular is one of those topics that is constantly evolving as more research is conducted so you are not alone if you’ve wondered if it's safe to put your baby to sleep on their side or if this can increase the risk of sudden infant death syndrome (SIDS). One of the key safe sleep recommendations when putting babies to sleep is to place the baby on their back from birth to sleep, to reduce the risk of SIDS and aim to prevent fatal sleeping accidents. This recommendation endorsed by the AAP has largely contributed to a significant decline in SIDS rates since the now called Safe to Sleep campaign began. 

Why Side-Sleeping Can Be Risky for Newborns

If a baby sleeps on their side it can look super cute and comfy but unfortunately, once a baby rolls on their tummy, they are no longer in a safe sleep position.  By rolling onto their tummy, they can compromise their airway and as their responsive reflexes are still developing, it can be difficult for them to respond to the roll safely by lifting their head or swallowing. By placing them on their back for all naps and nighttime sleep, you are providing the baby the safest sleep position to allow for clear airway protection.  

Increased risk of SIDs

Side-sleeping can increase the risk of SIDS and SUDI and once a baby rolls onto their stomach, they are potentially now blocking their airways. With developing neck and head control, they may then struggle to reposition themselves safely so placing a baby on their back to sleep is always recommended. Sleeping on their back is also a safe choice as it helps keep the airway above the esophagus, making swallowing easier which is an important reflex that helps protect their breathing.

When Is It Acceptable For Babies Sleeping On Their Side?

Like all things baby, there may be circumstances where side-sleeping is required under medical supervision or as advised from a pediatrician. Always consult a trusted health professional if you have questions relating to your child and situation. 

It’s recommended to always place your baby on their back for sleep, at least for their first year of life. However, as they grow in strength and skills, once they master the art of rolling and can confidently roll onto their side, front to back and back again, it's usually a sign it's safe to let them fall asleep in the position they find the most comfortable. Until they can roll consistently though, it’s best to remain cautious and encourage them onto the back for sleep. When babies start showing signs of rolling, make sure you help them on their way and progress from sweet swaddler to arms out transitioner!

When To Seek Professional Advice

Sometimes the simplest of things can still feel overwhelming or not address your individual circumstance. If you need help, reach out to a trusted medical professional for tailored advice.

Why Quality Sleepwear Matters For Sleeping Positions

Another key factor in providing safe, comfortable sleep is considering what a baby is wearing. Too much fabric or fabric that is weighted, may cause overheating or cause a breathing hazard if the layers are too loose fitting and cover their mouth or nose. It is also very important to stop swaddling when your baby shows signs of rolling. Always pick swaddles by their weight and height to get the most accurate fit and be sure to choose a sleep bag that offers a gentle transition to arms free sleep.
