In the decades following the Second World War, mothers' experiences of loneliness, boredom and unhappiness were increasingly widely acknowledged. The language of postnatal depression came to be attached to this, but mothers organised around their own discontent in ways that challenged the medical model. Unhappy mothers draws attention to the social, political, and professional contexts within which knowledge about unhappy mothering developed. Drawing upon an extensive range of archival material, the book addresses themes around expertise, feminism, and the value given to lived experience.
