When Can Babies Sleep on Their Stomach Safely?
Learn when it's safe for babies to sleep on their stomach and how to reduce SIDS risk.
New parents are often bombarded with advice about baby sleep, but one of the most critical pieces of guidance is about sleep positions. Is it safe for babies to sleep on their stomach? What happens if your baby rolls onto their stomach during sleep? And when can babies safely sleep on their stomach? This article covers everything you need to know to ensure your baby’s sleep is as safe as possible.
Why Back Sleeping Is Recommended
The American Academy of Pediatrics (AAP) and other health organizations strongly recommend that babies sleep on their backs until they are at least 12 months old. This position significantly reduces the risk of Sudden Infant Death Syndrome (SIDS), which is one of the leading causes of death in infants under one year of age.
According to the CDC, in 2020, approximately 1,389 babies died of SIDS in the United States. Placing babies on their backs to sleep is one of the most effective ways to lower this risk.
What Is SIDS?
SIDS, or Sudden Infant Death Syndrome, refers to the unexplained death of a seemingly healthy baby, usually during sleep. Most SIDS cases occur before the age of 6 months. While the exact cause of SIDS is unknown, research has identified several risk factors, including:
- Stomach sleeping
- Overheating
- Soft bedding or loose blankets
- Exposure to cigarette smoke
- Sleeping on unsuitable surfaces, such as couches or adult beds
Risks of Stomach Sleeping
Allowing babies to sleep on their stomachs increases the risk of several serious issues:
Rebreathing
When a baby sleeps on their stomach, they may inhale the air they have already exhaled. This air is lower in oxygen and higher in carbon dioxide, which can cause the oxygen levels in the blood to drop. This is especially dangerous if the baby is face-down on a mattress or if something covers their face, such as a blanket, pillow, or toy.
Suffocation
Stomach sleeping increases the risk of suffocation. If a baby’s nose and mouth are blocked, they may not be able to take in the oxygen they need. This can happen if the bedding covers their face or if they roll onto something that blocks their breathing.
Overheating
Babies who sleep on their stomachs can get too hot. The mattress pushes against their body and prevents air circulation, leading to a buildup of heat. Overheating has been linked to an increased risk of SIDS.
Choking on Spit Up
If your baby is a spitter, sleeping on their stomach increases the risk of choking on spit up. When a baby is on their stomach, spit can pool around their mouth, and they may inhale it, leading to choking.
When Can Babies Sleep on Their Stomach?
Some babies begin to roll onto their stomachs during sleep as they grow stronger and more mobile. In many cases, this is considered safe once they can roll both ways on their own, usually around 5 to 6 months of age. However, it’s still recommended to always place your baby on their back to sleep until they are at least 12 months old.
If your baby consistently rolls onto their stomach during sleep, speak with your pediatrician to ensure their sleep space remains safe and supportive for everyone’s peace of mind.
Safe Sleep Environment
Creating a safe sleep environment is crucial for reducing the risk of SIDS and other sleep-related dangers. The AAP recommends the following:
- Always place your baby on their back to sleep.
- Use a flat and firm sleeping surface, such as a crib or bassinet.
- Keep the crib or bassinet free of soft objects, including pillows, blankets, stuffed animals, and loose bedding.
- Share a room with your baby, but not a bed.
- Avoid overheating by dressing your baby in light clothing and keeping the room at a comfortable temperature.
What to Do If Your Baby Rolls Onto Their Stomach
If you wake up in the middle of the night and find your baby sleeping on their stomach, gently roll them back onto their back. If your baby is able to roll both ways on their own, it is generally considered safe for them to remain on their stomach during sleep, but always start by placing them on their back.
Swaddling and Safe Sleep
Swaddling can help keep your baby feeling snug and secure while they sleep on their back. However, it’s important to stop swaddling once your baby shows signs of rolling. Swaddling a baby who can roll increases the risk of suffocation.
Supervised Tummy Time
While it’s not safe for babies to sleep on their stomach, supervised tummy time during waking hours is essential for a baby’s development. Tummy time helps strengthen neck, shoulder, and arm muscles and can prevent flat spots on the head.
Medical Exceptions
In rare cases, a baby with certain medical conditions may need to sleep on their stomach. Always consult your pediatrician if you have concerns about your baby’s sleep position due to a medical condition.
