Which of the following is a protective factor against Sudden Infant Death Syndrome (SIDS)?

Breastfeeding is considered a protective factor against Sudden Infant Death Syndrome (SIDS) due to several mechanisms. Research indicates that infants who are breastfed have a lower risk of SIDS compared to those who are not. One reason for this protective effect may involve the nutritional benefits of breast milk, which contains vital antibodies and anti-infective properties that support an infant's immune system. Additionally, breastfeeding promotes healthy sleep patterns and bonding, which can further enhance the infant's safety during sleep.

On the other hand, frequent use of infant sleep positions, such as placing an infant on their stomach or side to sleep, has been associated with an increased risk of SIDS. Similarly, using baby blankets or allowing infants to sleep with toys in their cribs can create a suffocation hazard and increase the risk of SIDS. Therefore, creating a safe sleep environment is essential in reducing the risk, which is why breastfeeding stands out as a significant protective factor.
