This article addresses the affective, emotional, and familial dimensions of urban everyday mobility. Drawing on theoretical inspiration from phenomenology, nonrepresentational theory, and mobilities research on the relational mobilities of children and families, the paper explores the everyday mobility of 11 households with children in the multimodal context of Copenhagen, Denmark. Following the conceptualization of everyday mobility practices as heterogeneous 'negotiation in motion', the empirical analysis investigates how the strong relational dynamics between household members are organized around affect, care, familial bonding, and the rhythms of everyday life, which shape spatial patterns of moving together and apart. A new qualitative method combining GPS tracking, mapping, and household interviews is explored to show how everyday patterns of relational mobility are filtered through spatial affordances, affective ambience, and the temporalities of the lifecourse to influence transport alternatives of route and modal choices.
