This article aims to analyze the emergence of building trust by the mothers of children from 0 to 3 years old towards the public Institution of Early Childhood Education - Instituição de Educação Infantil (IEI). The analyses of this dimension of the relationships between the family and the Institutions of Early Childhood Education have been made based on the concept of trust as developed by Anthony Giddens as he analyzed the consequences of Modernity. The presented analyses focus on the senses and significances built by the mothers regarding their choice for the daycare center as the support for the children's care and education. They are founded on qualitative research involving both individual and group interviews with mothers whose kids attend public Institutions of Early Childhood Education. The conclusions indicate that the mothers act on the process of building a relationship with the school regarding the establishment of trust relationships and the legitimacy of the choice for the IEI for their children since the first years of their lives. This is shown by their actions towards reducing the lack of family knowledge about the IEIs as much as by the will to construct a narrative about Childhood Education and its teachers which will offer them more security.
