Each year in the U.S., about 3,500 infants die suddenly and unexpectedly in their sleep. In about half of these deaths, doctors can’t find a medical reason to explain why, even after a complete review. When the doctor doesn’t have answers, the death is called sudden infant death syndrome (SIDS).
Experts say that all babies are at risk, especially those under 1 year of age. Babies are most vulnerable to SIDS up to 4 months old. One of the critical pieces to SIDS risk reduction is how the baby sleeps. Babies who are sleeping should be on their back. Research has revealed many risk factors for sudden infant death, and sleep position is the most important one. A baby shouldn’t sleep on their belly or side.
