What is the primary recommended sleeping position for infants to reduce the risk of sudden infant death syndrome (SIDS)?

The primary recommended sleeping position for infants to reduce the risk of sudden infant death syndrome (SIDS) is the back position. This recommendation is supported by significant research showing that placing infants on their backs to sleep dramatically decreases the incidence of SIDS.

When infants are positioned on their backs, the risk of airway obstruction and suffocation is minimized, as this position allows for unobstructed breathing. Additionally, the back position has been associated with a lower risk of rebreathing carbon dioxide, which can occur if an infant is positioned face down or to the side.

Public health campaigns, such as the "Back to Sleep" campaign launched in the 1990s, have greatly increased awareness and adherence to this practice, resulting in a noticeable decline in SIDS rates. In contrast, the side and prone (stomach) positions are linked to an increased risk of SIDS and are not recommended for infant sleep. The sitting position is not suitable for infants who are not able to sit up independently, as it does not provide a safe sleeping environment and could lead to other risks.

Thus, placing infants on their backs when sleeping is essential for promoting their safety and well-being and significantly reduces the risk of SIDS.
