Book excerpt: This book discusses LGBTI+ childhood from a critical, interdisciplinary perspective with the aim of contributing to a better understanding of the complex relationship between sexuality, gender and childhood. Placing adultcentrism at the centre of the analytical inquiry, the international range of contributors consider experiences and subjectivities of children, their families and significant contexts. Topics covered include public policies, professional practices and care provision, as well as the tensions and contradictions stemming from the logics of otherness and exceptionality which populate dominant discourses, representations and practices around sex and gender in childhood. This book is intended for researchers and students in gender studies, sexuality studies, education, health, childhood studies and sociology.
