Can newborns sleep on their side?

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 from Red Nose 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 has largely contributed to an 80% reduction in SIDS deaths since 1989 so it’s an important one to remember.

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 oesophagus, making swallowing easier which is an important reflex that helps protect their breathing.

When Is It Acceptable For Babies to Sleep On Their Side?

Like all things baby, there may be circumstances where side-sleeping is required under medical supervision or as advised from a paediatrician. 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 their backs 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!
