This paper focuses on how a colonial logic shaped ideas and practices about childhood in the modern/colonial interplay between family members, knowledge, activities, and goods that combined difference, structural subordination, and modern adult-child relations in Colombia. Based on a local magazine directed by elite women, it refers to the cultural mechanism that merged northern and central perspectives with the regional and national modern/colonial horizon of family, public and private sex roles, children, and the broader framework of modernization between 1926 and 1940.
