This article highlights initial findings from a qualitative research study in Aotearoa/New Zealand exploring the discursive production of children's sexuality in early childhood education. The article draws attention to teacher talk about and around sexuality. Drawing from heteronormative, developmentalist and biological discourses and discourses of children as asexual and innocent, this article shows that such talk acts to normalize or minimize children. Teacher resistance towards and silencing of sexuality, the functions the silences serve and the ways in which silences mark the borders of "normal" and "abnormal" are uncovered. The article suggests that the marking of borders jeopardizes teacher acknowledgement and celebration of difference and diversity. Gaps between the rhetoric of celebrating difference and diversity and the reality of practice are emphasized.
