Analyzing surveys from 230 first-time mothers at Penn State, Dr. Ian Paul, a pediatrician, found that babies slept for longer stretches if they didn't sleep in the same bedroom as their parents. At 4 months, babies who slept alone had the longest stretches of uninterrupted sleep -- by about 45 minutes, on average -- though they slept about the same amount of time as babies who slept in their parents' rooms.Babies who slept in their parents' rooms slept for shorter periods, a new study findsA leading pediatrics group recommends room-sharing with infants until 1 year
