What age does the risk for SIDS significantly decrease after?

The risk for Sudden Infant Death Syndrome (SIDS) significantly decreases after 12 months of age. Research indicates that the majority of SIDS cases occur before 6 months, with rates continuing to decline through the first year of life. By the time an infant reaches 12 months, they typically have more developed physiological controls, such as improved sleep regulation and arousal responses, which contribute to a lower risk for SIDS. Additionally, factors such as the ability to roll over and a more advanced physical development play a role in enhancing the infant's safety during sleep.

SIDS is most prevalent in infants under 1 year of age, particularly between 2 to 4 months, making it crucial for parents and caregivers to follow safe sleep practices during this time. As infants grow beyond 12 months, the incidence of SIDS becomes very rare, leading to a significant decrease in risk after this age.
