What is SIDS?
Swaddling, a method of wrapping an infant securely in a blanket or cloth, is a common infant care practice in many cultures.81 Some researchers suggest that swaddling reduces the risk of SIDS because it helps infants sleep more comfortably on their back. If an infant startles while asleep, his own body movements can cause him to wake up. Swaddling can limit those movements and help an infant feel secure.82
However, SIDS researchers caution that swaddling can contribute to overheating. It is critical to teach parents and health care professionals how to properly swaddle infants if an infant is to be swaddled. Usually swaddling is effective only during the first 4 to 6 weeks of life. It should then be discontinued as the infant grows and becomes more mobile.
