ABSTRACT The purpose of this article is to show when and how the dialogical-discursive approach began to serve as a basis for thinking about the language acquisition process in Brazil and abroad - especially in France. This theoretical line seeks to analyze - the speech of children starting from the discursive movements found in the relationship between the child and his or her interlocutor (other), taking into account the situational contexts, the dialogism, the constitution of the subject in the speech, (...) etc. Thus a) we refer to the authors responsible for this approach, in a retrospective; b) we explain the theoretical aspects mobilized during the data analysis of children's speech; and c) we utilize the methodological aspects involved in this theoretical perspective. Our aim, therefore, is to discuss not only this other way of looking at children's language, but also the theoretical and methodological challenges that this approach brings to this specific field of investigation.
