Abstract
In this paper, we aim to clarify two central assumptions, which allow to specify what justice for children implies in the Capability Approach. First, we argue that an adequate currency of justice for children consists in a bundle of functionings, which develops into a bundle of capabilities in the course of childhood; the currency of justice for children is dynamic, not static. Second, we discuss how the respective functionings and capabilities should be selected. In particular, we suggest four criteria. They imply that there is not only a change through time from a bundle of functionings to a bundle of capabilities as the currency of justice for children, but that the composition of the bundle itself gets modified.
