Many are the devices that directly or indirectly act in the process of formation and constitution of subjectivities. Children's literature books are understood as important cultural artifacts that act in the process of education and identity construction of the subjects, specifically the children for whom the books are intended. This dissertation aims to analyze how children's books approach and construct discourses on sexual diversity and homoparentality, as well as to problematize the identity effects resulting from the production of such discourses. For that, three books have been identified and selected-Olivia has two parents, My two parents and I have two parents-with themes related to sexual diversity and homoparentality. They were analyzed from the social constructionist perspective that understands the language as an instrument that allows to found, to make sense, to include and to marginalize, to produce identities and relations between the subjects. According to our analyzes we understand that the three books present important questions for institutions as naturalized in our society as, for example, family and parenting. However, it is common in the three works to use subtle mechanisms that point to the creation of a gay family model, that is, books with their entanglements, dramas, characters and speeches present a hygienist and normalizing bias. The study also points out the need for other studies to analyze the books that have themes related to sexual diversity and homoparentality, as well as a review of the works analyzed here, since there is no single truth and that from other perspective it is possible to reach other conclusions.
