Taylor and Leitz trace processes of collective identity construction and politicization among women suffering from postpartum psychiatric illness who have been convicted of infanticide. Joining a growing body of research suggesting that self‐help and consumer health movements can be a significant force for change in both the cultural and political arenas, Taylor and Lietz examine one such movement, a pen‐pal network of women incarcerated for committing infanticide. Taylor and Leitz show how a sense of collective identity fostered by the pen‐pal network triggered a profound emotional transformation in participants, allowing them to convert shame and loneliness into pride and solidarity, and encouraging their participation in efforts to change how the medical and legal system treat postpartum psychiatric illness.https://digitalcommons.chapman.edu/peace_books/1000/thumbnail.jp
