This book reviews literature and research linked to early childhood education and care (ECEC). This educational level is fundamental for acquiring key competencies for school entry and establishing the physical, cognitive, and emotional bases for lifelong learning. Preschool education should promote student autonomy as the ability of a child to act on their own free will because it is a critical part of learning for all children. When a child has autonomy, it helps build confidence for responding to the demands of the family, self-esteem values linked to collaboration tasks, and independence in selecting reasonable choices.
