This volume brings together 16 essays by sociology and other scholars from the US, the UK, and South Africa, who discuss the barriers, struggles, resilience, and resistance of mothers marginalized for various reasons, from incarceration to immigration, and how their identities, such as immigration status, race, class, disability, sexuality, and age, impact expectations, treatment, and choices. They address the barriers that these mothers face, including with welfare, surveillance and policing, and in achieving their aspirations, as well as by mothers of children with disabilities; the borders of marginalized mothering, with discussion of Chinese mothers who give birth in the US, Mexican-immigrant mothers in the US, migrant mothers, incarcerated mothers, and migrant nannies; and mothering as resistance, in terms of maternal support, care work strategies used when they have met their lifetime limits on welfare, black women's home schooling experiences, breast milk sharing, and black activist mothering against police brutality.
