Social-emotional development refers to the process through which individuals learn to understand and manage their emotions, establish positive relationships, and develop social skills. This development is crucial during early childhood, as it lays the foundation for future interactions and emotional well-being. Key aspects include recognizing feelings, expressing empathy, and building friendships. Factors influencing social-emotional development include family dynamics, cultural background, and experiences in settings like preschool or daycare. Supportive environments, such as those provided by parents and teachers, play a significant role in helping children navigate their emotions and social interactions effectively.
