Building AI Literacy at Home: How Families Navigate Children's Self-Directed Learning with AI

As generative AI becomes embedded in children's learning spaces, families face new challenges in guiding its use. Middle childhood (ages 7-13) is a critical stage where children seek autonomy even as parental influence remains strong. Using self-directed learning (SDL) as a lens, we examine how parents perceive and support children's developing AI literacy through focus groups with 13 parent-child pairs. Parents described evolving phases of engagement driven by screen time, self-motivation, and growing knowledge. While many framed AI primarily as a study tool, few considered its non-educational roles or risks, such as privacy and infrastructural embedding. Parents also noted gaps in their own AI understanding, often turning to joint exploration and engagement as a form of co-learning. Our findings reveal how families co-construct children's AI literacy, exposing tensions between practical expectations and critical literacies, and provide design implications that foster SDL while balancing autonomy and oversight.
