The Argentine psychoanalyst Paulina Redler formulated the concept of abuelidad (grandparenthood), to denominate the relation and function of the grandparents and their grandchildren and the psychological effects of the relations between them. The concept of abuelidad is related to the function of transmission of the generational knowledge of the past to the grandchildren’s generation. We refer to different situations of the family life that in-terfere with the good intergenerational communication between grandparents, parents and grandchildren like the cases in which grandchildren are in the middle of the other generations as a trophy in dispute, when there are problems of jealousy or when the excessive narcissism of grandparents interferes with the possibility of approaching their grandchildren. In other cases, communication is favored when it is possible to have a good contact between grandparents and grandchildren, which is a situation that enriches both generations: the grandparents function as both narrators of the familiar saga and spokespersons of the trophic messages of the origins, of nutritious myths. Facing the challenges of the social present, grandchildren can take charge of the task of going ahead with the vital forces opposed to the destructive ones proposed at present. Finally, we comment that in clinical practice the tri-generational approach can help many of the conflicts between generations.
