What can trans, nonbinary, and gender-expansive people expect from pregnancy? What roles do supportive friends, family members, and care providers play? What are some of the fabulous family structures folks are creating? This collection brings together a wide spectrum of voices to share unique stories about navigating family building, pregnancy, fertility treatments, conception, loss, healthcare, abortion, childbirth, the early days of parenting, and the intersections of legal, political, and cultural contexts. Alongside individual stories, this book features collaborative round-table discussions where contributors address shared questions about personal journeys, community, advice and information, and pregnancy care. Seahorses is both a vital resource for trans, nonbinary, and gender-expansive communities and an invitation for readers of all genders to get a glimpse of trans joy and resilience that will stick with you and inspire you to love a little deeper.
