In this chapter, we explore the Dutch situation on parental guidance of young children’s media use. Since 2009, several scientific research projects on parental mediation have been supported by our ministries of Welfare and of Culture and produced practical outcomes. The empirical knowledge has laid the foundation for evidence-based parenting support, which contributes to the safe and playful use of the internet and the development of digital skills of children, both at home and in schools and day-care centers. For teachers, librarians, doctors, and workers in day-care centers, training programs are developed to make them more knowledgeable about children, media and parental mediation. As always in an evolving research agenda there are the “known unknowns”. Therefore, this chapter concludes with a sketch of the white spots in our knowledge and a brief agenda for future research.
