Full Summary

Detransition, Baby opens one month after conception, establishing a temporal structure that defines the entire novel. The narrative alternates between two timelines: the weeks following conception, which track the pregnancy's progression, and flashbacks to years before, which reveal the characters' histories and the roots of their present choices. This dual structure creates a rhythm of urgency and reflection, as the pregnancy's countdown presses forward while the past is slowly uncovered.

The central situation involves three characters whose lives converge around an unexpected pregnancy. Ames, who detransitioned after living as a trans woman named Amy, has impregnated his boss, Katrina. He proposes that Reese—his former girlfriend, who is deeply invested in the idea of motherhood—join them in raising the child. The discussion questions in the novel's Book Club Guide confirm that the book explores how Reese, Katrina, and Ames's feelings on motherhood differ and converge, and that the novel imagines an alternative family configuration beyond the nuclear family.

The flashback structure reaches back to two distinct periods: eight years before conception and three years before conception. These temporal shifts suggest that the novel traces the long arc of the characters' lives, showing how past decisions, relationships, and losses led them to their present situation. The eight-year flashback appears in Chapters Two and Four, while the three-year flashback appears in Chapters Six and Eight, creating a pattern of alternating between past and present throughout the book's first half.

The pregnancy timeline progresses steadily: one month after conception in Chapter One, six weeks in Chapter Three, seven weeks in Chapter Five, eight weeks in Chapter Seven, ten weeks in Chapter Nine, eleven weeks in Chapter Ten, and twelve weeks in Chapter Eleven. This steady progression creates a sense of mounting urgency as the characters must decide what to do about the pregnancy.
