Cultural ideologies surrounding motherhood represent powerful frameworks for shaping women’s experiences within that role and tend to assign greater value to experiences that fall within a traditional family framework. However, many women’s experiences of motherhood do not fit within this framework. The experiences of double mothers – women who have both biological and stepchildren – can highlight the identity work that women perform in blended families. Balancing the cultural expectations of biological motherhood with the challenges of stepmotherhood, many double mothers occupy a space in-between, and perform regular boundary work to navigate their roles.
