By contrast, regular prenatal care does reduce risk. Together, these are called sudden unexpected infant deaths , which includes both sudden infant death syndrome and deaths from suffocation, asphyxiation, strangulation and other preventable deaths. Of the many resuscitations of infants she has attempted over the years, she says she hears the same thing from every parent: "We didn't think it was going to happen to us. The group recommends against parents and infants sharing a bed, sometimes called co-sleeping, because of a significantly increased risk of death from suffocation or other causes. A period of neurodevelopmental vulnerability is thought to be a major factor in SIDS, and both skin-to-skin contact and breast-feeding contribute to neurodevelopmental maturity and normal respiratory breathing patterns, Feldman-Winter explained. So they're offering advice on how to reduce the risk of bed sharing with infants, which includes removing loose bedding that could lead to suffocation. As before, relying on years of strong evidence about the risk factors for these deaths, the AAP recommends that infants be placed to sleep on their backs on a firm mattress in their own crib or bassinet, with no blankets, sheets, pillows, stuffed animals, crib bumpers, positioners or other items.
