Sleep is important for health, yet little is known about sleep in foster and kinship families. In my postdoctoral fellowship, I will lead research to learn about the sleep health, how best to support sleep, and the connection between sleep and caregiver-child relationships for foster/kinship families. In Study 1, we will synthesize research on children’s sleep in foster and kinship care. In Study 2, we will interview foster and kinship caregivers of children aged 0-5 years to learn about the caregiver and child’s sleep, and how sleep influences the caregiver-child relationship. In Study 3, we will compare sleep in foster and kinship families with other families in Canada. In Study 4, foster and kinship caregivers will help us design and test a sleep resource. We are creating an advisory panel to work with us to create research that is useful and interesting to the foster/kinship community, and respectful of different cultures and family dynamics. With the advisory panel, we will share the results in journal articles, at conferences, via webinars, and through foster/kinship organizations. This research will help healthcare professionals and policymakers understand, and help support, the sleep of families in foster and kinship care.
