Today's children are busy. From the same kindergarten ages, they are exposed to all kinds of activities. When they start school, they become occupied with school schedules, assignments, learning and even extracurricular activities. At a later age, liabilities only increase. However, excessive scheduling often causes a feeling of overload which can ultimately affect problematic behavior and emotional challenges. Therefore, spare time is extremely important for children. It is simply necessary, either for rest, entertainment, or for exploring one's own interests or for carefree enjoyment with friends and/or parents, or for developing social competencies at one's own pace. The possibilities are endless, but it is necessary for the child to spend his spare time according to his wishes. Guided by the fundamental theme of the work Active use of spare time of children of early and preschool age, the importance of children's spare time will be interpreted and based on the conducted research, it will be shown how they conduct it. For the purpose of the research, an online questionnaire method was used in which a total of 105 respondents participated. The results of the research showed that 85,7% of children spend their free time in active play, and play is one of the most natural ways preschoolers spend most of their time. Most children engage in physical activity recreationally, as indicated by the fact that children do not engage in any organized sports activity that includes a sports club or any organization, but 72% of parents believe that their child spends their free time well. The fact that 75% of parents encourage their children to engage in physical activity in their free time is very positive nowadays when neither parents nor children have time to spend their free time better due to obligations.
