Sleep disruption and motor development: Does pulling-to-stand impacts sleep-wake regulation?

Research output: Contribution to journalArticlepeer-review

Abstract

During the second half of the 1st year, periods of increased sleep disruption have been documented alongside overall improvement in sleep-wake regulation. The objective of the present research was to test if pulling-to-stand (PTS), a milestone typically achieved during the latter part of the 1st year, co-occurs with a period of disrupted sleep. In a longitudinal design, 20 healthy infants were followed-up, from 7 to 11-12 months, at 3-week intervals. Each measurement consisted of filmed motor observations and sleep recordings (actigraphy), both conducted at home. It was found that among early achievers of PTS (by 8 months), the milestone was time-linked to a period of disrupted sleep. The results point to the significance of timing in the interplay between domains of development, and highlight the importance of considering both chronological and developmental metrics in studying changes in sleep-wake regulation.
