Gadget use among toddlers in Nagari Malalak Barat, Malalak District, Agam Regency, West Sumatra, has increased rapidly, yet many parents still lack adequate understanding of how to supervise children's gadget use safely, including managing screen time, selecting age-appropriate content, and preventing digital dependency. This community service activity aimed to strengthen parents' understanding of digital parenting to support healthy gadget use among toddlers. The activity applied a Participatory Action Research (PAR) approach carried out through five stages, namely assessment, planning, action, evaluation, and reflection, in which parents were actively involved in identifying problems, designing solutions, and reflecting on the outcomes. It was held on 4 July 2026 in Nagari Malalak Barat and involved 12 parents of toddlers, all of whom completed both the pre-test and post-test. Data were collected through observation, group discussion, documentation, and a simple pre- and post-test, then analyzed descriptively. Results showed that the participants' average understanding score increased from 57.14% before the activity to 78% after the activity, along with participants' initial commitment to limiting screen time and providing closer supervision of their children's gadget use. The main contribution of this activity is a contextual, replicable digital parenting education model built on a leaflet and educational module that can be reapplied through Posyandu activities at the nagari level. The results of this activity lead to the conclusion that the PAR-based approach is effective in enhancing parents' understanding and participants' initial commitment in the short term, although long-term behavioral change still requires ongoing monitoring.
