Design/methodology/approach: Relativist narrative inquiry is outlined as a theoretical and methodological approach to expand sociological research on motherhood and sport, by exploring big and small stories on social media sites. Elite athlete mother's mediated self-portrayals on Instagram are theorized as identity stories (re)created and made possible, by cultural narrative resources.

Findings: An example of big and small story research is outlined from a larger case study of elite athlete figure skating mothers' self-portrayals on Instagram as they negotiated motherhood, and a professional sport career. Thematic narrative analysis findings include a big story plot in the post-partum period: negotiating intensive mothering and career. Two small stories that fed into fluid meanings of this big story plot are also presented: holding the baby close and working mum/new mumtrepeneur. These findings show nuanced contradictions of contemporary motherhood meanings, within sportswomen's personal and public digital stories.
