For instance, it has been suggested that the physical restraint associated with swaddling may prevent infants placed supine from rolling to the prone position.299 One study's results suggested a decrease in SIDS rate with swaddling if the infant was supine, 182 but it was notable that there was an increased risk of SIDS if the infant was swaddled and placed in the prone position.182 Although a recent study found a 31-fold increase in SIDS risk with swaddling, the analysis was not stratified according to sleep position.171 Although it may be more likely that parents will initially place a swaddled infant supine, this protective effect may be offset by the 12-fold increased risk of SIDS if the infant is either placed or rolls to the prone position when swaddled.182, 300 Moreover, there is no evidence that swaddling reduces bed - sharing or use of unsafe sleep surfaces, promotes breastfeeding, or reduces maternal cigarette smoking.
