This article analyzes the possibilities and obstacles in pedagogical practices in ECEC (Early Childhood Education and Care) in relation to developing relevant opportunities for participation for all children, by supporting their own engagements in order to expand their action possibilities. Over the last decades, the political agendas in the Nordic as well as other OECD countries have been led by an increasing focus on learning goals and standardized professional procedures, at the expense of a more situated and flexible pedagogy following children’s own engagements. When concerns arise about children’s well-being, development, and/or learning, this tendency seems to intensify, as descriptions of concerns are often based on assessments of children’s individual (dis-)abilities, while investigations of children’s own engagements and reasons for actions are seldom conducted. From a theoretical standpoint in critical psychology and social practice theory, we discuss collaborative processes among children and adults in relation to institutional conditions as inherently political, in the sense that the distribution of different access to social resources and opportunities for participation for different children is negotiated through such daily exchanges and therefore also involves questions about democracy. We explore the everyday life practices of children and professionals, analyzing how, through everyday practice, they constantly work on maintaining, reproducing, and transgressing the standardized demands. To understand such processes, we suggest a conceptual focus on the politics of everyday life and situated pedagogy.
