This research seeks to relate the Design approach in partnership with the daily school life of Early Childhood Education and ways of including children with autism. The term inclusion, which started to be disseminated in the 90 s, has as a principle that everyone has access to Education, regardless of their condition. Qualitative exploratory and interpretive research had data collection techniques as bibliographic and documentary research, field observation and world café dynamics. The research maintains that the Design in Partnership approach can be applied in the daily school life of Early Childhood Education, through experimentation, given the context that many teachers have never lived with children with autism and are also learning ways to relate, creating an inclusive culture. With the partnership of actors who are on the school floor, who are present in all stages of the design process, it is possible to create materialities from the interests of children with autism or with communication difficulties, enhancing their forms of interaction. The analysis of data through interactional sociolinguistics showed that interaction, a pillar of early childhood education and one of the difficulties of people with autism, is facilitated when there is a convergence of welcoming, knowing and experimenting. It is concluded that characteristic actions of Design in Partnership can be replicated by teachers in Early Childhood Education, enabling a Design of Welcoming by: knowing - the coexistence and observation of the interests of children with autism; experiment - propose a diversity of materialities, observing the actions and possible potentialities.
