The media are an integral part of the lives of adults, and they are increasingly used by children as well. It is almost impossible to imagine a child of early and preschool age who is not exposed to some kind of digital devices on a daily basis. The change in the environment in which children grow up is related to digital content and represents a significant challenge for parents and experts who have the task of protecting and guiding children in the virtual world. The use of digital content provides various opportunities such as entertainment, developing competences, learning, finding information, up to the creation of addictions and exposure to the dangers of the virtual world. The impact of digital technologies will depend on the content the child consumes and the time spent using digital content. In the empirical part, research is presented, conducted through a questionnaire among parents of children of early and preschool age. The results show that a child spends an average of 1.2 hours a day using digital devices. Parents (90.2%) believe that digital content affects their child's behavior, but 45.3% of them declare that they do not use protection on the devices on which the child views digital content. Parents are obliged to take care of children's digital literacy, educate themselves about the effects of digital technologies on children and protect them from potentially harmful content. We cannot isolate children from digital content, and the positive effects of the media can be used for the purpose of their complete development.
