This paper analyses how traditional gender divisions are negotiated, reinforced, or redefined in digital kinwork. Drawing on two qualitative projects, we examine how platformization intersects with gender and generational roles in practices of care, coordination, and recognition. We first provide an overview of common digital kinwork practices, then explore the gendered divisions that shape them, and finally show how platforms redistribute expertise and structure micro-power within family relations. Our findings reveal that digital platforms function as infrastructure for family life, with women often being the first to adopt messaging apps and social platforms, unlike past patterns where men led in technology use. Yet their expertise is framed as caregiving rather than prestige. We argue that digital kinwork extends beyond intimacy and connection, encompassing micro-power, the distribution of recognition, boundary-setting, and the negotiation of ambivalent relations of care and control.
