Description of intervention(s) / exposure
Within childcare services direct observations of sleep practices and sleep policies are conducted in rooms catering for infant [0-18 months] and toddler [18-36 months] aged children (n=40 rooms) via a standard intensive in-situ observation measure: The Sleep Observation Measure for Early Childhood Education and Care (SOME; Staton et al, 2015). The SOME is a multi-item observational tool used to collect detailed records of sleep environments, sleep practices and children’s behavioural responses within childcare settings. Observations are conducted on a single day in each childcare settings, commencing at approximately 9am and ending at approximately 2:30 pm). Educators within each service also complete a brief survey regarding current sleep policies, including parent-educator communication strategies. Outcomes data is collected at two time-points (baseline and 6 months following initial observation).

Eligibility
Key inclusion criteria
Direct observations of sleep practices are conducted across 40 childcare rooms (one each of infant [0-18 months] and toddler [18-36 months]), sited within 20 long day care childcare services and 6 family day care rooms. To capture a range of social and developmental profiles, services are randomly selected from within stratification of small local areas identified by the AEDC as of high, moderate and low vulnerability. All families with children aged 0-36 months attending target childcare rooms are eligible to participate.

Statistical methods / analysis
Since this is a highly innovative exploratory study with no precedence in the literature, there are no previous data on which a credible sample size calculation can be based. Thus, as explained in Bacchetti et al. it would be inappropriate to conduct such as sample size calculation. Rather, the proposed sample size is based on our experience with related outcomes. The anticipated sample is approximately 200 children, based on a conservative mean uptake of 5 children per room, consistent with our prior studies recruited in this way.

Descriptive analyses will be conducted to examine sleep practices and child sleep patterns. Regression analyses will be conducted to examine the relationship between childcare sleep practice and children’s sleep patterns and behaviours. Analyses will model concurrent and follow-up outcomes and consider both the independent effects of childcare practice and concordance of home and childcare sleep practices on children’s sleep health. Child, family and service characteristics will also be measured and included as controls.

Summary
Brief summary
The early years of life are critical in development of sleep behaviours and present the optimal window for promotion of healthy sleep patterns and early intervention to prevent and treat sleep problems. During this period, childcare plays a significant role in the lives of children and has demonstrated impacts on lifetime trajectories of health and development. This project focuses on the role of childcare in supporting sleep health of children aged 0-3 years.
The majority of Australian children attend childcare and many spend considerable hours in
childcare from early life, when sleep patterns are developing. Despite this, little is currently
known about impacts of childcare practices on young children’s sleep health. Yet prior to age 3, there are substantial challenges in this context that result from greater variability in child sleep need (including timing, duration and number of sleep periods), settling behaviours, and the complexity of parent demands. This study aims to examine current sleep practices for infants and toddlers (aged 0-36 months) in childcare settings. The focus is on addressing two key questions in establishing the role that childcare plays in younger children’s sleep health:
(1) Do childcare environments influence children’s sleep patterns and behaviours?
(2) Does consistency between sleep practices in childcare and at home influence the regularity of children’s sleep patterns?
