This article introduces Karleen Pendleton Jimenez's book for young children, "Are You a Boy or a Girl?", represents a landmark achievement in queer literature in the early childhood classroom and deserves special attention by pre-school and primary teachers, academics working in early childhood education, and parents, particularly parents with gender nonconforming children. It takes a great step beyond books like "William's Doll" (Zolotow, 1985) and "Oliver Button Is a Sissy" (DePaola, 1990) and opens up a conversation among young children about the rigidity of gender roles and "appropriate" activities and behavior for boys and girls. This book is important because it could be the start of classroom-based interventions to support gender nonconforming children in schools. At this point, throughout the United States and Canada, classroom teachers must take their own initiative in creating resources and support for these children. At best, gender nonconformity is addressed through new, anti-bullying curriculum or through a discussion of "tomboys" in gym class. Jimenez's book has seen strong utilization in Toronto area schools and one can hope that this classroom practice will result in program and curriculum development in the near future.
