Children’s rights, promoted by United Nations through the Convention on the Rights of the Child (CRC) (1989), have been ratified and incorporated into the States legal systems, nevertheless difficulties still exist to integrate them into the specific policies and programs design for this group of population.The historical paradigm of modern childhood since nineteenth century moves away shyly to give way to the children’s citizenship paradigm, but continuing with an adult-centered approach. It is a winding road in which it is obvious that the rights of children and adolescents are inherent in their status as citizens. Thispaper addresses the relationship between childhood and right, from a holistic approach, trying to identify the lack of effectiveness and commitment of public policies with children’s rights taking into account the important vulnerabilities and forms of social exclusion that child and adolescent integral development is suffering.
