Abstract Children, or people under 18 years-old, represent 30% of the world population. While Childhood Studies gained attention in the last decades, in Brazil this topic remains incipient. In 2022 the Group of Studies on Childhoods and International Relations (GEIRI) mapped the open depositories for dissertations of Brazilian universities with IR programmes to understand how children appear as an IR issue. Using the framework of Global IR, this article presents two main contributions by analysing this novel data: a) ontological contribution by understanding Childhood Studies as a Global IR topic and Brazilian practices and interactions to see IR outside of a Western perspective and b) methodological contribution by analysing how students contribute to the IR knowledge production on Children and IR in Brazil mostly as international security and human rights issues. 1 yearsold, yearsold years old, old years-old 30 population decades incipient 202 GEIRI (GEIRI issue data b issues 3 20 2
