Early childhood extends from ages 2 to 6, while late childhood extends from ages 6 until puberty. In early childhood, physical growth slows compared to infancy. Children develop motor skills like running, jumping, and balancing. Psychosocially, children develop initiative through play and assertiveness during preschool years. In late childhood, growth rates increase again with teeth development and body proportion changes. Children conform more to peer groups and develop skills in school. Psychosocially, school-aged children's sense of competence and pride forms through social interactions and encouragement from others.
