[The construction of childhood and its specialized medical care: the beginnings of pediatrics in Buenos Aires, 1890-1920].

It analyzes the set-up of pediatrics as a specialized medical field in Buenos Aires, between 1890-1920. The article seeks to demonstrate this process as a result of two movements: the delimitation and characterization of children as a particular object of knowledge and intervention, and the institutionalization of some physicians as a professional group that sought to legitimate their specificity within the medicine field and beyond. After contextualizing socially and historically the concerns of medical knowledge on childhood, it explores with detail how the field was constructed, and the associative and academic movement that allowed pediatricians to constitute themselves as a group of specialists that bear a specific expertise.
