Updated recommendations from the American Academy of Pediatrics highlight critical steps to lower the risk of Sudden Infant Death Syndrome, including sleep positioning, environment controls, and lifestyle factors aimed at protecting babies during their most vulnerable months.
Sudden infant death syndrome, or SIDS, remains the unexplained death of a baby younger than 1 year after a full investigation, including an autopsy, medical history review and laboratory testing, fails to identify a cause. The Centres for Disease Control and Prevention says it sits within the wider category of sudden unexpected infant death, which also covers accidental suffocation and deaths that remain unexplained. In the US, SIDS is the leading cause of death after the newborn period.
Most cases occur early in infancy. According to the material cited in the original article, 90% of SIDS deaths happen in the first 6 months, with the highest concentration between 1 and 4 months. Risk is higher when babies are placed on their side or stomach to sleep, when they are born prematurely or at low birth weight, or when the sleep environment includes soft surfaces, loose blankets or bumper pads. A family history of SIDS or failure to thrive is also listed among the risk factors.
The American Academy of Pediatrics recommends that every sleep should be on the back, on a firm, flat surface without an incline. It also advises room-sharing, but not bed-sharing, for at least the first 6 months, with the baby sleeping on a separate infant sleep surface close to the parents’ bed. The academy says breast milk feeding is linked with a lower risk of SIDS and recommends offering a pacifier at nap time and bedtime, while delaying pacifier use until breastfeeding is established, usually at around 3 to 4 weeks.
Other guidance focuses on reducing avoidable hazards. The academy says soft items, including pillows, quilts, comforters, stuffed toys and loose bedding, should be kept out of the sleep area, and parents should avoid smoke, nicotine, alcohol, marijuana, opioids and illicit drugs during pregnancy and after birth. It also advises against overheating and head covering, recommends regular prenatal care and infant immunisation, and says home cardiorespiratory monitors should not be used as a SIDS prevention strategy. Supervised tummy time while the baby is awake is encouraged to support development and reduce positional plagiocephaly, or flat spots on the head.
