Based on the premise that children are active agents who influence their parents’ media use, this study investigated child–parent digital media guidance. Children often introduce new media into the family and influence parents’ media adoption and use. This study also investigated whether this child–parent digital media guidance is associated with media conflicts in the family. A cross-sectional survey was conducted among 187 parent–child dyads in Flanders, Belgium. Paired samples t-tests and multiple linear regression analyses were conducted. The results showed that both children and parents reported that children guide their parents how to use digital media, especially for newer media forms such as smartphones, tablets, and apps. Families where there was more child–parent digital media guidance reported more conflicts about media. These relationships were comparable in the parent and child reports.
