Peer reviewedSt James-Roberts, Ian; Plewis, Ian – Child Development, 1996
Used multilevel analyses to examined the amounts of time infants spent asleep, awake, content, feeding, fussing, and crying at 2, 6, 12, and 40 weeks of age. Found that day-to-day fluctuations accounted for between 44 and 53% of the variance in amounts of time sleeping, fussing, and crying. (MDM)
