We analyse two foundational social problems regarding early childhood education. The first, in the late nineteenth century, is infant mortality, a social problem that constituted the historical legitimation for the first creches. The second, the prevention of school failure, is very topical today. By analysing these examples in their historicity, taking into account social, political, economical and scientific contexts, it becomes clear that early childhood education can contribute to the individualisation and decontextualisation of social problems. Yet acknowledging this also means opening windows of new opportunities, as far as the construction of social problems remains an open debate in which disagreement rather than consensus is fostered.
