Children's literature helps young people make sense of gender. However, while books offer children the imaginative ability to create their own worlds, normative gender can manifest in characters and stories. The study described in this article draws upon "disruptive" storytimes with 114 preschool children, interviews with 20 parents and staff, and observations at 20 preschools. Employing a feminist, queer approach, I develop two derivative books that switch a boy-hero for a girl and vice versa. These books are read to children in educational settings. This method interrogates gendered characters and stories' attachments to such concepts as love, acceptance, bodily agency, and adventure. Results show how children interact with these characters and stories and how they use categorisation and narrative construction to make sense of gender. I focus on the gender discourses at play and moments of childhood discursive agency. Themes include literature, doing and being, positioning, bodies, and feminist tales.
