Middle childhood is a developmental stage that typically occurs between the ages of 6 and 12 years. During this period, children experience significant growth in physical, cognitive, and social skills. They become more independent, develop friendships, and begin to understand complex concepts in subjects like math and science. This stage is crucial for emotional development as children learn to manage their feelings and build self-esteem. They also start to engage in organized activities, such as sports and music, which help them develop teamwork and discipline. Overall, middle childhood lays the foundation for adolescence and adulthood.
