Why Stomach Sleeping Seems Better, But Back Sleeping Is Safest
Share
You’re exhausted. You’ve tried everything. You rewatched the swaddling video multiple times, yet your newborn still won’t settle. Then you remember what your grandmother said: “Babies sleep better on their stomach.” Grandma isn’t wrong. Many babies do sleep longer and deeper on their stomachs. But the real question is: Is it safe?
As a pediatric nurse practitioner and former NICU nurse, I’ve struggled with this question myself. In the NICU, when a premature baby was having a rough day, placing them on their stomach often seemed to help stabilize them. But as babies approached discharge, our focus shifted to modeling safe sleep. In a crib, they were always swaddled and placed on their backs. So, why the shift?
Stomach sleeping does help babies feel more contained and reduces startling. That’s why they seem to sleep more soundly. But this deep sleep can dull the ability to fully wake if oxygen levels drop, increasing risk for infants, especially before they have the ability to roll on their own. That’s why the universal recommendation remains: place babies on their backs to sleep.
Understanding the “why” helps, but I know that knowledge doesn’t erase the exhaustion you feel when your baby won’t sleep. In those moments, swaddling or using a swaddle sleep sack until your baby shows signs of rolling can help minimize startling and provide gentle containment.
Safe sleep guidance should be about education, not fear. We shouldn’t just say “do this,” we should explain why. Putting babies on their backs in a clear sleep space, on their own, reduces the risk of SIDS (sudden infant death syndrome) and SUID (sudden unexpected infant death). These risks can feel scary, but my goal is to empower you with information, not fear. With the right information, you can make informed choices that help reduce the risk and build confidence in your safe sleep routine.
If you're looking for simple, supportive safe sleep education, I created a free Safe Sleep Made Simple guide designed to help parents feel more confident in their safe sleep routine during the early newborn weeks.
