Clinical inquiries: What are safe sleeping arrangements for infants?

Non-supine sleep position and parental tobacco use are known risk factors for sudden infant death syndrome (SIDS). Recent studies show that co-sleeping (bed sharing) slightly increases the overall risk of SIDS (strength of recommendation [SOR]: B) and is greatest for infants less than 11 weeks old (SOR: B). The relationship between bed sharing and SIDS is strongest for infants whose parents use tobacco (SOR: B). Infants who sleep in a room separate from their caregivers or on a couch or an armchair are at increased risk for SIDS (SOR: B). Using bedding accessories such as duvets or pillows may increase an infant's risk of SIDS (SOR: B).
