The study draws on a relational and intersectional approach to young children's belonging in Finnish educational settings. Belonging is conceptualized as a multilevel, dynamic, and relationally constructed phenomenon. The aim of the study is to explore how children's belonging is shaped in the intersections between macro-, meso-, and micro-levels of young children's education in Finland. The data consist of educational policy documents and ethnographic material generated in educational programs for children aged birth to 8 years. A situational mapping framework is used to analyze and interpret the data across and within systems levels (macro-level; meso-level; and micro-level). The findings show that the landscape in which children's belonging is shaped and the intersections across and within the levels are characterized by the tensions between similarities and differences, majority and minorities, continuity and change, authority and agency. Language used, practices enacted, and positional power emerge as the (re)sources through which children's (un)belonging is actively produced.
