Negotiating Adult-Child Relationships in Early Childhood Research presents a substantive critique of technicist and neoliberal approaches to ethics through an exploration of the complicated and often `messy¿ situations faced in negotiating relationships in research with children. Drawing upon data from their own research, the authors contend that relationships are part of a wider web of social relations and space-time configurations. They propose and develop a relational ethics of answerability and social justice, inspired by the work of Bakhtin, and in addition explore the way material bodies come to matter, the ambiguity of consent in educator-research, and the risks and possibilities of research relationships. Chapters include innovative formulations of reciprocity, `sensing practices¿, and political-ethical responsibility.
