This book brings together the work of researchers from around the globe around the topic of children’s first transitions to early care and education. It discusses political and sociocultural contexts, theories, and ideologies around the theme. The book offers perspectives and findings on adult expectations around a child’s first transition, infant emotional experiences, the role of space, the part that key objects play in infant transitions, and the role of time. It also discusses age of first entry, routines and rhythms of the institutions, and the future expectations of those involved. The book takes a culturally responsive approach, revealing at times striking commonalities across countries, and at other points distinct differences in the people, environments, orienting pedagogies, and policies that inform an infant’s transition into care.
