Objective:To compare sleep‐wake patterns of breastfed and formula‐fed preterm infants.Design:Data were taken from an exploratory study of infant biorhythm maturation. Parents completed a 24‐hour diary of infant Sleep, Awake, and Cry states and feedings, recorded at 30‐minute intervals. Infant health data were collected from medical records and parents’reports.Setting:Infants were studied in the home after discharge from a neonatal intensive‐care unit.Participants:The convenience sample included 12 breastfed and 25 formula‐fed preterm infants (gestational age, 26–33 weeks; corrected postnatal age, 4–6 weeks). Groups were comparable in terms of gestational age, postnatal age, Apgar scores, maternal age, and home environment.Main Outcome Measure:The 24‐hour recording period was divided into day (0600‐1800) and night (1800‐0600). Study variables were Day, Night, and 24‐hour Sleep, Awake, and Cry.Results:Breastfed preterm infants exhibited more Day Cry and 24‐hour Cry than did formulafed infants. Infants demonstrated a diumal pattern in Cry, Awake, and Sleep. Breastfed preterm infants cried approximately 1 hour per day more than formula‐fed infants.Conclusion:Preterm breastfed infants experienced more cry than did formula‐fed infants. The relationship between feeding method and sleepwake pattern has implications for supporting lactation as well as for research design.
