In a world that is responding to ever-changing ideas and expressions of gender, this book adds new insights on transgender children and the parents who support them. Drawing on in-depth interview data with more than fifty parents, the book examines parents’ shifting understandings of their children’s gender and how they come to help their children make sense of their identities and their bodies. Throughout these processes, the book shows that parents’ meaning-making and decision-making often challenge LGBT rights discourses, as well as queer political tenets, in unexpected ways. These dynamics surface in three key areas: (1) gender and sexuality, (2) the gender binary, and (3) the body. Throughout parents’ understandings, gender identity and sexual orientation do not always present as radically separate aspects of the self, but are more fluid and open to reconsideration, given new cultural contexts, opportunities, and phases of the life course. And despite increasing cultural visibility around nonbinary identities, “gender-expansive” child-rearing often looks, fundamentally, very binary and gender-stereotypical, per the children’s own assertions and expressions. Lastly, parents often utilize highly medicalized understandings of transgender embodiment, which nevertheless resonate with some children’s sensibilities. Altogether, these families depart from conventional understandings of gender, sexuality, and the binary, but in ways that prioritize child-centered shifts, meanings, and parenting models, not necessarily LGBTQ politics or paradigms. This marks new ground for understanding the mechanisms and parameters of the (trans)gender change afoot.
