The aim of the study is to investigate preschool educators' perceptions of children's need for sleep and rest in preschool as well as their experiences of cooperating with the home regarding the child's sleeping times, based on the child's needs. Our goal is to investigate how a claim from guardians regarding children's sleep in preschool is met by educators. To do this we search the answers of the following three questions: How do educators view children's need for sleep and rest in preschool and how do they respond to guardians demands for children's sleep? How do educators reason about good communication with guardians? What consequences do the educators think the dialogue with the guardian can have for the child's sleep and rest in preschool? To get the answers of these questions we have done ten qualitative interviews with female preschool educators. The study is based on a phenomenographic perspective, where we want to create an understanding of how educators perceive the phenomenon of sleep and rest in preschool. As children's need for sleep is something that is communicated about in the interpersonal meeting between educators and guardians, the importance of the relationship and the treatment will also be emphasized from an educator's perspective. To analyze the relationship and communication as concepts we use the social constructivist theory. The results we got through this study shows that all educators agree that the preschool should offer an environment where children get the opportunity to rest and sleep for a day full of activity, this to manage a whole day in preschool. Rest and sleep seem to be a routine that is adapted to needs, both after the childrens and guardian needs. Therefore we ask ourselves, whose needs are the most important, the childrens, guardians or both? The results also show that the preschool educators have different opinions about which competencies that are important when it comes to having good communication about sleep with guardians. Every pedagogue says that a certain competens is needed just because the communication is of such importance for a good cooperation between home and preschool.
