Child development theories are frameworks that explain how children grow and learn over time. These theories focus on various aspects of development, including cognitive, emotional, social, and physical growth. Notable theorists like Jean Piaget and Lev Vygotsky have contributed significantly to our understanding of how children think and interact with their environment. Different theories emphasize different stages and processes of development. For instance, Erik Erikson proposed a psychosocial development theory that outlines eight stages, each characterized by a specific conflict that must be resolved for healthy development. Understanding these theories helps parents, educators, and psychologists support children's growth effectively.
