Picture books are often part of children's socialisation processes, contributing to the children forming images of the world, including ideas about (categories of) people, such as nurses. The study aims to explore how nurses/nursing are portrayed in children's picture books in a Swedish context. Through a systematic search, 44 books were included for analysis using thematic analysis and a theoretical lens inspired by Goffman. The results were presented in three themes: 'The costume characterised and designated nurses', 'Nurses and nursing were defined through specific activities and accessories', and 'Nurses' role as caregivers and decency practitioners'. The results showed that nurses were depicted/described in varied contexts, performing their roles mainly front stage in 'hands-on work' in close contact with patients and relatives. Nurses were attributed different accessories and personality characteristics. Nurses/nursing were generally set within a healthcare context, oftentimes within an overarching medical logic. Historical depictions of nurses'uniforms still appeared as a signifier for nurses/nursing. The presentation of nurses/nursing might have potential implications on children's understanding of and for reputations of nurses/nursing in the long term as primary socialisation and related understandings of the (sub)world(s) are deeply rooted in humans.
