This investigation studied the role of grandmothers in relation to the care they gave to their grandchildren through the question: How has the task of being grandparents been to you? This was studied through a dialogical method postulated by Shotter (1999) and supported by other authors, which implies abandoning the hierarchical relationship between investigator and object of investigation, with the purpose that the investigator gets involved as another participant and interacts with them. There were meetings organized with the grandmothers where they were asked the main question and other topics emerged from that. This method was applied in 3 different contexts: Nimaima, Sabio Caldas and 20 de Julio. According to the information collected from those encounters, categories emerged which were useful for the analysis of the dialogues in relation to the theory developed by Harris y Meltzer (1990) about the family functions. Furthermore, an analysis of the consequences on the use of this methodology for the investigation and the investigators. In terms of what was found in relation to the grandmothers and the different contexts, certain nurture tendencies characterized each one, but there were also meeting points between all contexts. Nimamima's grandmothers tend to take charge of all the child care, in Sabio Caldas the grandmothers used physical punishment and a very firm education and in 20 de Julio the child care they had with their own children served as learning so that they didn't repeat the same mistakes with their grandchildren.
