Some babies appear to feel more comfortable when sleeping on their stomachs. This prone position allows them to roll over and move more freely, which may be more enjoyable for babies who are starting to become more active. But is it truly safe for babies to sleep on their stomachs?
Risks of Sleeping on Their Stomachs
The prone position increases the risk of Sudden Infant Death Syndrome (SIDS), a condition that can occur even in seemingly healthy infants, usually during sleep.
Studies have shown that babies who sleep on their stomachs are at a higher risk of SIDS compared to those who sleep on their backs. This is because the prone position can interfere with the baby's breathing, especially if the sleeping surface is soft or if there are soft objects like blankets, pillows, or toys nearby.
Apart from SIDS, other risks linked to babies sleeping on their stomachs include:
Breathing Difficulties
When babies sleep on their stomachs, there's a chance their airway could be blocked by the mattress, blanket, or other items in their surroundings. This can make it difficult for babies to breathe or cause them to re-inhale the air they exhale.
Increased Temperature
The prone position can also make babies feel too warm, particularly if they are overdressed or sleeping in a hot environment.
Unstable Head Position
Babies who sleep on their stomachs tend to experience more pressure on one side of their heads, which can affect blood circulation to the brain.
When is It Safe for Babies to Sleep on Their Stomachs?
Once babies can change their sleeping positions on their own, sleeping on their stomachs becomes safer. Typically, by 4-6 months of age, babies develop enough strength to roll from stomach to back or vice versa.
With the ability to shift positions, the risk of suffocation decreases. Still, parents should ensure that the baby's sleep environment remains safe by using a firm, flat mattress and avoiding pillows, blankets, or toys in the baby's crib.
Tips for Babies Who Prefer Sleeping on Their Stomachs
Some babies naturally enjoy sleeping on their stomachs. To ensure their safety while sleeping, here are some helpful tips:
- Always place your baby on their back to sleep, even if they prefer being on their stomach.
- Once your baby can roll over and change positions, you don’t need to adjust their position, but always place them on their back when they first fall asleep.
- Make sure your baby sleeps on a firm, flat mattress without any pillows, thick blankets, or toys nearby.
- Offer tummy time during waking hours to strengthen neck and upper body muscles, helping your baby learn to roll back onto their back if needed.
- Avoid using pillows or bolsters to hold your baby in place, unless specifically advised by a doctor and supervised closely.
- Ensure the baby’s room temperature is comfortable—not too hot or too cold.
- If your baby consistently rolls onto their stomach, monitor them closely while they sleep.
By following these precautions, you can help keep your baby safe even if they prefer sleeping on their stomach. If you have any concerns about your baby's development or health, don’t hesitate to consult a pediatrician. You can also access health consultations through the Ai Care app, available for download on the App Store or Play Store.
