When we imagine life behind the high walls of the fortress-like prisons that were built and modified as the modern prison system was created in the mid-nineteenth century, we conjure up scenes where strict regulation prevailed to control people in body and in mind. An image that poses something of a paradox is that of mothers and their babies living in this carceral environment. This book looks behind the cell doors of these institutions to illuminate the experiences of this group of prisoners. The management of their health alongside the management of penal discipline posed complex conundrums to the prison system. Although rarely fully considered at policy level, this balancing act was negotiated by those who lived and worked in prisons on a daily basis. -- .
