The preschool years are a sensitive period during which, with appropriate support, children can develop various skills and discover their talents. Understanding the importance of early stimulation for optimal child development has led to the emergence of various organized extracurricular acti- vities, whose diveryity meets the interests of a large number of children. Organized activities, a- mong which sports, artistic, language, and scientific programs are the most prevalent, affect va- rious aspects of a child 's development, including cognitive, physical, socio-emotional, and lingu- istic development. Through sports activities, children enhance their motor skills and develop a sense of teamwork; artistic activities allow them to express creativity and develop emotional in- telligence and language and scientific activities foster intellectual abilities and stimulate curiosity. Participation in organized activities allows children to explore themselves outside of the family and institutional contexts, gain new acquaintances and knowlege, which positively impacts their self-image as competent young individuals. These activities enable children to chanel their energy into creative expression, physical exercise, and learning through play through structured yet flexible programs. For children to fully engage in organized activities, they need support from they immediate surroundings, consisting of parents and preschool teachers. Parents, as primary organi- zers of leisure time, support children in choosing activities that align with their interests and abili- ties. On the other hand, preschool teachers, through observing the child's needs and preferences, provide stimulating and safe enviroment in which the child can freely explore and learn, while also collaborating with parents to discover and develop the child's interests. Additionally, society plays a crucial role in integrating children into the life of the local community to develop a sense of belonging and solidarity. This paper explores the importance of organized activities in the preschool years as a foundation for further child development and emphasize the need for colla- boration between parents, preschool teachers, and the local community in supporting child's deve- lopment.
