Abstract:
Observed the sleep–wake patterns and interactions with caregivers of 9 premature (aged 28–35 wks) and 28 full-term (aged 37–42 wks) infants in their homes at 2–5 wks postterm. The 7-hr observation day was divided into times when the S was alone and times when the S was with the mother. Premature Ss spent more time alone than full-term Ss. Premature Ss spent more time in alert activity, nonalert waking activity, and sleep–wake transition than full-terms, and less time in drowse and total sleep. Results indicate that prematures exhibit significant commonality in neurobehavioral development through the early postterm period despite similar exposure to prenatal, perinatal, and early postnatal stresses.
