The aim of the research was to examine the media literacy of parents of preschool children. 303 respondents (281 women and 22 men) participated in the study. The theoretical part of the paper talks about media literacy, media literacy research and how we can educate ourselves for the media. It is known that children are surrounded by the media from an early age and that it is the parent who first serves the children various media. Therefore, in this paper we can see how the media can positively and negatively affect children, but also what is the role of parents in the relationship between the media and the child. The research questions asked in the survey are as follows: What is the attitude of parents towards social networks, do they use them and to what extent? Do parents use media content well and to what extent do they allow their children to stay in front of the media? Do parents see the media as an advantage or a danger in their children's lives? At what age would children be allowed their first cell phone? The results of the research showed that almost every parent has their own profile on a social network, that more than half of the respondents post photos / videos of their minor children on one of the social networks. However, a small number of parents state that they allow children to spend more than two hours a day by the screens. Also, it can be concluded that parents in theory are well aware of the advantages and disadvantages of using the media, but in practice they do not stick to it.
