The availability, affordability, and desirability of quality child care are matters of concern, especially for children raised in poverty, given the literature showing that young children raised in poverty can benefit from early access to quality care. The unique features of the Brussels context enable us to look at the connection between availability and parental preferences, while "controlling" environmental constraints on costs and quality. We looked at access policies in 83 funded providers, and examined 100 mothers' search for child care. The results show that quality child care was distributed unequally, favoring higher-income groups. Moreover, the access policies of individual providers furthered the exclusion of lower educated and ethnic minority parents. All parents took into account both quality and pragmatic criteria when looking for early child care, although the value of these criteria may vary according to ethnic background and education. The study also shows that access to and use of good quality care is an interactional process in which the mothers' preferences and decisions are affected by the availability of care which, in turn, is determined by external conditions.
