Placing infants on their backs to sleep is critical because it has been proven to decrease the risk of SIDS, a leading cause of death in infants aged 1 month to 1 year. Research has shown that the sleep position of infants has a direct impact on their SIDS risk, with those sleeping on their stomachs or sides being at a higher risk. The "Back to Sleep" campaign has been associated with a more than 50% reduction in SIDS cases since its inception.
