What is SIDS?
Prone sleep position, environmental and prenatal tobacco exposure, overheating and illegal drug exposure are considered risk factors for infants because research indicates infants are more likely to experience negative outcomes when their environment includes one or all of these variants. Some factors, such as pacifiers, swaddling and breastfeeding are speculated to protect infants against SIDS. For example, it is clear that breastfeeding clearly results in improved infant health. What is unclear is how these practices are protective against SIDS specifically.
