Childhood development refers to the physical, emotional, and cognitive growth that children experience from birth to adolescence. During this time, children learn essential skills such as walking, talking, and socializing. Factors like family, education, and environment play a crucial role in shaping a child's development, helping them build a strong foundation for future learning and relationships. As children grow, they go through various stages, each marked by unique milestones. For instance, toddlers begin to explore their surroundings, while school-aged children develop critical thinking and problem-solving skills. Understanding these stages helps parents and caregivers support their child's journey, ensuring they thrive in a nurturing environment.
