Overheating is also associated with SIDS. New parents are often concerned about keeping baby warm, but too many layers of clothing and blankets may actually make it harder to breathe. If baby's in warm clothes, no blanket is needed. If baby's in thin pajamas, a thin blanket is fine. Keep it tucked below baby's chest. As for swaddling, it's comforting for many infants, but once baby falls asleep, try to gently unwrap the receiving blanket or move it down below the baby's chest.
