This chapter offers a new framework for analysing the child’s right to development. The framework is based on a number of key elements. First, it is situated within the broad protection of ‘child development’ in the UN Convention on the Rights of the Child. Second, it promotes the protection of child development as a human right of children, rather than as a matter of welfare or charity.1 Third, it utilises a hybrid conception of childhood that departs from the dichotomy of the ‘human beings’ and ‘human becomings’ models, and provides greater respect for children’s agency. Fourth, it draws a clearer distinction between the meaning of the right to development as a guiding principle of the Convention and its distinct meaning as an independent human right of the child. Using this framework in conjunction with a cross-disciplinary understanding of child development can lead, I argue, to the creation of a more comprehensive and concrete interpretation of the child’s right to development.
