This book presents new ethnographic research carried out with five children between one and five years old. It explores children's agency in relation to daily transitions across everyday life contexts such as home and day-care contexts. Based on this new research, Pernille Juhl shows how young children are active participants orientating in their everyday life transitions. She argues that we should understanding children as creative and transformative subjects co-creating together with co-participants such as parents, professionals and other children, the conditions under which they live. Juhl builds on theoretical work by Holzkamp, Stetsenko, Hedegaard and Vygotsky and covers a range of theoretical approaches and concepts in her analysis such as befindlichkeit, micromovements and embodied orientation. While the research was carried out in the Danish context, the broader theoretical discussions are relevant for early childhood contexts globally, with a focus on Europe and the USA.
