This book explores the experiences of a group of Australian women who became first-time mothers between 1950 and 1965. A grounded theory of transformative power in motherwork is presented that has emerged from the analysis of interviews. The mothers talked about what they did in their active mothering years. The author argues that despite being constrained by the gender bias in the patriarchal context, these mothers were agents who developed skills that enabled them to resist or creatively deal with most of the constraints they faced. Their emphasis was on their agency and the power to nurture their children into responsible adults. Their awareness of the importance of their motherwork acted as a motivator in this development.The author further argues that the relationship between each mother and each of her children is a transformative power relationship in which both mother and child are transformed—the child into an independent adult and the mother into a skilled self-motivated agent through her motherwork. Any threat to this process resulted in the mother doing all she could to resist or counteract the constraint/s she was encountering. Transformative power expressed in motherwork can be recognised analytically by several characteristics. It empowers both parties in the mother–child duality. Complexity, diversity, fluidity, and responsiveness to the physical, intellectual, and emotional aspects of the relationship are all evident in transformative power relationships.
