We assume that the construction of encounters that produce care is a participative practice in health. Drawing on different research that has explored care production from a micropolitical approach, we present a view of participation as embedded in everyday life and based on the construction of encounters and relationships. Our goal is to provide reflections for debate on participatory practice within different frames of action. Based on the analysis of different cartographic narratives generated by research on a reproductive health policy, we discuss some core elements for the construction of encounters that produce care. On the same lines as models of professional development based on professionals' day-to-day experiences, we propose experimentation during the encounters and discussion about what happens in them, as both a reflective practices and forms of collective and participative knowledge production.
