Sleep/Wake States of Preterm Infants: Stability, Developmental Change, Diurnal Variation, and Relation with Caregiving Activity.
Ingersoll, Evan W.; Thoman, Evelyn B.
Child Development, v70 n1 p1-10 Jan-Feb 1999
Used time-lapse video to record sleep/wake states of preterm infants for three 24-hour periods at 33 and 35 weeks conceptional age. Found that very-low-birthweight preterm infants showed marked stability and developmental change in the organization of sleep/wake states from a very early age, and their states were related to demographic variables and temporal measures of caregiving.
