The purpose of this qualitative study is to listen to young children who live in favelas regardingtheir knowledge about their rights. We listened to a group of six children between the ages of five and six who are residents of the Rio favela, Rocinha, about what they consider important to their well-being. The proposed reflection, the theoretical, methodological and conceptual references chosen reflect the position that children are central subjects in a study and should be listened to, as a right. The testimonies and views of the children were analysed contrasting their knowledge within relation to their rights. The results point out to the importance of listening to and learning with the children without losing sight of the conditions in which they live which result from various inequalities and injustices that characterize life in a favela. We conclude that despite the fact that the notion of listening to childrenas a right is already part of the debates, in fact their voices have little value in public policies and social practices. The study helped us understand that when children s voices are valued by adults, there are gains that can contribute to the commitment to young children and their rights.
