Based on the analysis of the projects - (i) Naif para Nenéns, of the International Museum of Naive Art in Brazil, in Rio de Janeiro and (ii) No Colo, of the Tomie Ohtake Institute in São Paulo, both developed during the year of 2016 - the present dissertation sought to understand the inclusion of infants in education programs in art museums. Some questions guided this research: What are the proposals developed for the public from zero to three years in the studied institutions? What is the intention of the educators in offering actions for this segment? What strategies were develop for babies to interact with the collection and the other participants? How do babies interact with the activities offered, with their peers and with adults? The methodological resources used were: (i) semistructured interviews with those responsible for the propositions and with accompanying adults of the babies; (ii) observation of the activities; (iii) documentary analysis; (iv) photographies. In its theoretical basis, research was guided by the studies of Child Development, such as Vigotiski and Tomasello, and Aesthetics such as Vecchi. Based on the research and analysis of the practices in question, in dialogue with the theoretical framework adopted, it has been found that contact with artifacts, collective experiences and sensory experimentation proposals can be significant for the socioemotional and cognitive development of infants. The inclusion of this public gives opportunities for new ways of being and thinking about the exhibition spaces, contributing to its democratization and enlargement about the posibilities of mediation.
