Childhood development refers to the physical, emotional, social, and cognitive growth that occurs in children from birth to adolescence. This process is influenced by various factors, including genetics, environment, and experiences. Key milestones include learning to walk, talk, and interact with others, which are essential for overall development. During childhood, children develop important skills such as problem-solving, communication, and emotional regulation. Play is a crucial aspect of this stage, as it helps children explore their surroundings and learn about relationships. Supportive environments, including family and school, play a vital role in fostering healthy development.
