This work aims to create narratives of Rua Sete de Setembro, in the Center of Vitória (ES), in rupture to the dominant strata that treat it as an empty place. Therefore, we bring the concepts of infantilization and becoming-child closer to architecture and urbanism in its relation to ways of living, using and writing in the city. We consider infantilization as a strategy of the capitalistic subjectivity production machine that removes the individual capacity to think and organize life. The concept of becoming-child, in turn, refers to the lines of escape, processes of deterritorialization, focus of a micropolitics that acts in everyday life experience and connects with the perception of children before they being modeled by the productive equipment. Accessing the becoming-child is about entering into the field of experimentation, subverting adult logic and abandoning the mask that imposes limits, domestics and discourages. We assume this work as a methodological approach incorporated by becoming- child to research, manipulate and write with the affection felt by our vibrating body of cartographer-researcher at searching for other becoming-child in the city. Such affections, seemingly random encounters, came through field research and documentary collections. With them, we created a database of heterogeneous documents in their species and data - photographs, newspaper snippets, correspondence and official publications, maps, architectural designs, interviews, and logbook annotations. The documents were taken as fragments in which we play in chapters-blocks of photographs-drawings-tales-discussions. The thematic choice of each chapter-block was guided by the tension between attempts at infantilization and becoming-child in and around the city and it was related to the use of public space by children; to the street carnival; and to the dispute over street use, especially in bars and their sidewalk tables. At Rua Sete and its surroundings streets this tension is alive at least from the end of the nineteenth century. The way we present this work seeks to highlight the possibilities of document combinations and to indicate the potential of the becoming- child to think, to narrate cities and to review the island of Vitória from other angles and eyes.
