The purpose of this study is to reflect on the need to perform a historical-discursive approach to contextualize and analyze in a critical way hospital and nursing discourses and practices related to spaces to play in pediatric infirmaries at hospitals. The Statute of the Children and Adolescents, made into a Federal Law in 1990, is a document that guides a new vision concerning the field of childhood and youth. Among the consequences of the ECA, there is the establishment of a different mode for the adult to relate with children, and that the effects on healthcare should assume and effect changes and transformations in the hospital scenario. We have tried to show the need to problematize and contextualize how our hospital scenario is determined by discourses that operate silently. In order to resist to the effects of such devices, health and nursing practices should be rethought and rectified in their respective disciplinary devices.
