Babies should always be placed to sleep on their backs to reduce the risk of Sudden Infant Death Syndrome (SIDS) during their first year of life. It is considered unsafe for babies, especially newborns up to 5 months, to sleep on their stomachs because it significantly increases the risk of SIDS and other breathing-related hazards. However, once a baby can roll over independently both ways—from back to tummy and tummy to back—usually around 5 to 6 months old, it is generally considered safe to let them sleep in the position they prefer, including on their stomach. At this stage, babies have the strength and motor skills to lift or turn their heads to breathe properly even when on their tummy. Despite this, the American Academy of Pediatrics and other health experts recommend continuing to place babies on their backs to sleep until they are at least 12 months old. If a baby rolls to their stomach during sleep, it is usually okay to leave them there if they can roll back on their own. In summary:

• Place babies on their backs for all sleep until they are 1 year old.
• Babies can safely sleep on their stomach once they can roll both ways independently (usually after 5 to 6 months).
• Always ensure the sleep environment is safe (firm mattress, no loose bedding).
• Consult your pediatrician if you have concerns.

These guidelines help reduce the risk of SIDS and ensure safe sleep practices for infants.
