This article explores the movement of children between households in Zambia as a site of ‘moral navigation’. Moral navigation extends Henrik Vigh's concept of social navigation from contexts of conflict and migration to more socially stable contexts in which well-being depends critically on people's ability to manage relationships. The live, dynamic and mobile character of these relationships means that they require active, real-time cultivation and response. While having practical objectives, these negotiations are also moral, articulated with ideas of what ought to be, and seeking to fulfil sometimes competing ethical projects. Life history interviews present three main perspectives: recollections of times in childhood spent away from birth parents; birth parents’ reflections on having a child living with others; and adults’ accounts of taking in other people's children. Strong norms of kinship unity and solidarity notwithstanding, in practice terms of engagement are differentiated through gender, marital, social and economic status, plus relational and geographical proximity. The pursuit of personal benefit contains the seeds of both contradiction and convergence with the collective good, as a relational understanding of moral selves sees one's own gain as proper, rightful and virtuous when it is realized in and through providing for others.
