The Safe to Sleep campaign, formerly known as the Back to Sleep campaign,[1] is an initiative backed by the US National Institute of Child Health and Human Development (NICHD) at the US National Institutes of Health to encourage parents to have their infants sleep on their backs (supine position) to reduce the risk of sudden infant death syndrome, or SIDS. The target age group of the campaign is 0–1 years of age, because this is when babies are at the greatest risk of experiencing SIDS.[2] Since "Safe to Sleep" was launched in 1994, the incidence of SIDS has declined by more than 50%.[2] However, there has been a rise in infant sleep-related suffocation events. Consequently, the campaign has broadened its goal to focus on safe sleep conditions and further preventative measures.
