Drawing on ethnographic research conducted among parents living in the affluent neighbourhoods of Ipanema, Brazil, and El Condado, Puerto Rico, I examine how urban Latin American elites deployed their parenting practices as moral justification for their racial and class privilege (what I call ‘sovereign parenting’). One way in which they do this is by producing particular forms of affective relationships with their nannies. The women these upper-class parents hired were largely dark-skinned immigrants: from the Dominican Republic, to work in El Condado, and from the Brazilian Northeast, to work in Ipanema. I demonstrate how elites cultivated a form of ‘informality’ and expressions of care in relation to childcare workers in ways that not only produced whiteness as a pillar of Latin American liberalism, but also associated whiteness with the world of interiority and personal growth.
