This paper traces a conversation between the authors about their long-standing (Urban) and more recent (Gómez Muñoz, Zárate Pinto) engagement in and with RECE. The conversation revolves around the role and potential of reconceptualist thought in contexts of early childhood realities in the Global South, most prominently in Latin America, where two of the authors are based, while one has extensive work connections to the region. Given RECE’s roots in US-American and English language worlds, what other approaches exist in Latin America contexts and beyond that enable us to challenge the dominant narratives of early childhood education, its narrow disciplinary base, its policies and practices? Drawing on work with marginalised communities, the conversation turns to necessities of advocacy and transdisciplinarity, and to possibilities of epistemic and new activist alliances.
