The different strategies explored by parents managing their children’s digital practices, the associated challenges, and the conditions for a successful outcome are central in the literature on digital mediation within families. However, few studies consider the family context in its entirety, which is essential if we wish to capture the meanings, perceptions, and negotiations that are played out in the daily family routine. Based on an ethnographic survey on the place of screens in Swiss families’ socialization processes, the paper shows, first, how paternal use undermines digital mediation within the family and, second, that this mediation is ultimately a maternal concern and responsibility. By interviewing all family members (including children) on their assessment of screen use by all family members (including parents), our research design provides access to the backstage of parental digital mediation. Our data shows that women confront fears and guilt in the face of social norms that a ‘good’ mother should regulate screens ‘well’ within her household. We conclude that parental digital mediation is embedded in a gendered social and relational context, where fathers and mothers do not adopt the same roles, the same duties, nor the same mental burden.
