This paper presents data from interviews undertaken with teachers and parents of children who attend Australian bush kinders (kindergartens). The bush kinder approach is a recent adaptation of the European and UK forest school approaches, one that continues to gain momentum as increasingly teachers and parents come to understand the benefits associated with this type of outdoor learning environment. The research was undertaken using ethnography (Delamont, 1992; Madden, 2012), a useful method of research in this type of setting as ethnography enables a deep understanding of how children 'notice' in nature over time. The paper applies a discourse analysis (Gee, 2011) of teacher and parent interviews critically exploring the learning and development benefits children experience from attending a bush kinder program. Findings reveal that through their noticing, preschool children make a transition from being nature novices to nature experts. The data demonstrate the benefits preschool children can gain from learning and being 'in' and 'with' nature and the important role adults play recognising young children's noticing in nature.
