The aim of this article is to report an intervention, based on the framework of Winnicott's theory, in a community toy library that serves children and teenagers in situations of social vulnerability. The methodology followed was action research: the strategy was the supervision of interns and toy librarians, collection of documentary data and narrative reports by residents, bibliographic research and intervention in the playroom. As a result, it was found that the relationships that were established, based on trustworthiness, reliability and consistency of actions, provided children and teenagers with a human environment that allowed spontaneous and creative play, making them less vulnerable to the challenges encountered. The intervention based on the assumptions of Winnicott's theory made it possible to expand the work beyond the individual relationships and strengthen collective practices, creating strategies of composition between the health and the social fields.
