A "child" is a young human being, typically defined as a person between the ages of birth and 18 years. This stage of life is characterized by rapid physical, emotional, and cognitive development. Children learn through play, exploration, and social interaction, which are essential for their growth and understanding of the world. During childhood, individuals go through various developmental milestones, including learning to walk, talk, and develop social skills. Education, often provided in settings like schools, plays a crucial role in shaping a child's knowledge and abilities. The care and guidance of parents and guardians are vital for a child's overall well-being and development.
