In November 2012, a researcher, two social workers and five mothers embarked on a participatory action research (PAR) journey with the aim to develop new ideas for interventions for children and young people in street situations of the city of El Alto in Bolivia. In this article, we attend to the topic of personal and social transformation in PAR. We explore how the mothers of young people in street situations perform and negotiate their subjectivities as mothers in their everyday life; how they create (new) subjectivities in exchange and in interaction with each other during the mother project; and how the performance of their (new) subjectivities can bring social change. The mothers in our group shared stories of being silenced by social services in their everyday lives, as their motherhood is declared not good enough or as they are perceived too guilty to claim for help. It was the first time the mothers shared their stories with other mothers of their lives with their children in street situations. By noticing that they all experienced or heard of similar events that their children were subjected to in the streets, the mothers grew confident enough to talk back. Mothers talked back by denouncing injustice and by transforming doubts into questions, providing them with more knowledge. Finally, as the mothers reached out to social services, mothers’ presence, questions and stories confronted aid workers with their own flaws, and their comfortable discourse of blaming families, creating new paths towards social transformation.
