Screens and their influence on the early development of children are an increasingly common topic. We live in a digital age and the influence of screens has become inevitable. With that, even the youngest have become skilled users of various screens. The long-term effects of screen use on children’s development are still unknown. Variouss tudies are being conducted; however, they have not provided answers to many questions yet. Although reasonable use, setting time limits and controlling the content viewed on screens is being emphasized, it is not recommended for children up to two years old to be exposed to screens at all. As the first three years are often emphasized as the most important for children’s brain development, the subject of this study is the impact of screens on brain development in children up to the age of three years. Since it is impossible to calculate given impact through classical research, the aim of this paper is to examine the perspective of parents on possible consequences of screen use on children’s brain development. For data collection, a questionnaire was used in which 550 parents of preschool children participated. The results of the research showed that parents mostly agree with statements about negative consequences of screen use on brain development in children. When it comes to the time that children should spend in front of a screen per day, the result was less than an hour. The largest percentage of parents gave the same answer to the question about their children’s amount of screen time per day. Considering the questions raised about the normality of development, no delays in the development of the respondents' children were found.
