Brief summary

The developmental significance of sleep transition in early childhood. This project aims to advance understanding of sleep functioning as children transition from many naps, to one nap, then none. Through an intense, objective longitudinal study of sleep from age one to five years, the project seeks to examine the interplay of sleep, care environment and ongoing child development. The project is expected to deliver much needed evidence to address the controversy surrounding care practice in family and early childhood education and care contexts. The expected benefit for parents and educators is improved knowledge and confidence in supporting children’s sleep. The expected benefit for children is positive development, given the known impacts of sleep on ongoing learning, behaviour and health.

Interventions

A prospective, longitudinal study of N=300 children aged 12 months (base-line) to age 5 years (school entry). Objective measurements of sleep patterns will be collected for two-weeks using a watch-like activity monitor (actigraphy), once every 6 months, across 8 data collection time points (i.e. approximately until children reach school entry). Exposure will be naturalistic, with children recruited from across community samples and observed as they undertake their daily activities (e.g. in the h

A prospective, longitudinal study of N=300 children aged 12 months (base-line) to age 5 years (school entry). Objective measurements of sleep patterns will be collected for two-weeks using a watch-like activity monitor (actigraphy), once every 6 months, across 8 data collection time points (i.e. approximately until children reach school entry). Exposure will be naturalistic, with children recruited from across community samples and observed as they undertake their daily activities (e.g. in the home, childcare settings and outside the home). Children’s participation will also include participating in iPad activities. Parent’s participation will involve answering surveys and installing a light and temperature sensor in their home. Surveys will include questions about children and their family including their experiences, their child’s height and weight, development and sleep.

Inclusion criteria

Inclusion criteria at the target regions will include all small local areas (SLAs) located in and surrounding Brisbane, Australia, with targeted recruitment in SLAs randomly selected based on the stratification frame. Inclusion criteria at the child level includes a child aged 9 to 12 months.

Exclusion criteria

Exclusion criteria at the child level includes significant medical, neurological, or developmental disorder, or out of home placement. Additionally, retention of families across the four years of the study is critical, therefore, families who do not wish, or perceive they will be unable, to participate in each wave of data collection, will be excluded from the study.
