Motherhood is changing. An increasing number of women are deciding to remain childless, having fewer children, postponing their transition to motherhood, and simultaneously pursuing careers. These changes are deeply embedded in a reconfiguration of the times of motherhood. Although the intersection of motherhood and time has been widely acknowledged by gender and feminist studies, less attention has been paid to how in the making of motherhood women reproduce, negotiate and subvert time mandates and norms. This article aims to underscore the importance of time and how it relates to the enactment of motherhood in contemporary societies by analysing the planning, timing, sequencing, and simultaneity of the transition to motherhood in Chile. Through the analysis of 15 life story interviews with urban women from Santiago de Chile, this article addresses the intersection between social change, motherhood and time by showing how in the making of the transitions to motherhood women reproduce, negotiate and subvert traditional and emergent cultural mandates and social norms on the times of motherhood.
