Technology has become an integral part of human life, and its influence can be seen in every business, educational and educational sphere. Even the youngest members of society have become adept at using technological innovations. Many point out that digitalization can have both positive and negative aspects on the development of preschool children. The positive aspects are the improvement of communication and the overall positive attitude that a child can have towards technology. The child's curiosity is greatly developed and learning is simplified. The negative aspects, i.e. the arguments that cause skepticism among parents, educators and the general public, are mostly the same for years: the child gets too used to and relies on technology, creative capacities are reduced, the research focus of the child is limited in a certain way because the child expects that information and fun content to come now. Additional skepticism is focused on the unfavorable effect on the physical condition of preschool children. Certain academics believe that children who rely too much on technology lose their will and ability to learn, communicate and socialize, and in addition, their natural physical capacities, which must be developed from a young age, decline. The fact is that man is a being that needs movement, not a sedentary lifestyle. In the literature, therefore, there are opinions that say that reduced physical capacities during the preschool age will become stronger and have a negative impact on a person's further life. The following lines explore the role of technology in the development of preschool children.
