Given the current societal and political trends toward increasing demands on women to provide care, a conceptualization of caring that captures the common processes of diverse women's caring experiences, and makes the consequences of caring for women's health visible, is critical for the development of a health and social policy that is responsive to women. The findings of this feminist grounded theory study go beyond the current theoretical understandings of women's caring, framed as either burden or fulfilment. The complex strategies women use to manage the dissonance created by competing and changing caring demands are revealed as a process I have named precarious ordering. This middle range theory demonstrates the power and resilience in women's management through the interdependent processes of setting boundaries, negotiating, and repatterning care. In addition, the method of theoretical sampling used in this study is explicated to move toward a formal theory applicable to diverse women's caring in a wide range of health, illness, and developmental situations.
