What Is the Peak Age for SIDS?
SIDS most often occurs between 1 month and 4 months of age, with the highest risk in the 2-month to 3-month window. The condition is rare after 12 months.
Why Is This Age Range Highest Risk?
During this period, infants are undergoing rapid brain and immune system development. Immature arousal and breathing control systems can make it harder for babies to wake or adjust during sleep.
How to Reduce SIDS Risk
Safe sleep practices are the most effective way to lower risk. Always place infants on their back to sleep, on a firm mattress, with no loose bedding, pillows, or toys in the sleep area. Room-sharing without bed-sharing is recommended.
For detailed guidance, see the safe sleep recommendations from the American Academy of Pediatrics at healthychildren.org.
