Content sharing is part of social networking, and social networks are part of the daily lives of a large number of the world's population. In this newly created environment, sharenting appeared and was defined, as a term that refers to the trend of publishing information about children by parents on social networks and other online services. The privacy of children in this context is becoming a burning issue, as all published information is recorded and creates a digital identity of the child. Although children's rights are legally regulated and protected, they are not adapted to the digital environment and fail to regulate what is needed. Children should be given the right to protect their data in an online environment, such as the GDPR, one of the items of which is the “right to be forgotten”. Although significant, such regulation does not completely solve the problem, because data once published on the Internet can always be recorded somewhere due to the possibility of data storage. For this reason, parental education is necessary to try to avoid this problem. The paper explores the habits and reasons for sharenting among parents who are members of three Facebook groups, and how much parents are aware of the problems and dangers that may arise as a result. The aim is to gain insight into awareness, i.e., familiarity with the basic concepts of sharenting and parental mediation, in order to gain insight into the state of knowledge of the problem. Drawing attention to the topic and its importance, and the importance of educating about it, was the main goal of the research.
