Positionality is a concept that acknowledges subjectivities, values and experiences of researchers as influencing approaches to and outcomes and implications of research; it underlines the importance of reflexivity and self-awareness. To understand how positionality is used in HCI, we conducted two studies: (i) a scoping review of positionality and reflexivity statements in the CHI papers in the last 11 years and (ii) a survey of HCI researchers (n=75). Our findings show that positionality statements are often a box-ticking exercise and their influence on the research is rarely discussed. While positionality statements are often used and requested in papers, they are often restricted to more sensitive areas of research and impact marginalised identities. We argue that positionality statements can be valuable but not as markers of methodological rigour. Our contributions include a current snapshot of positionality in HCI and reflections on the role of positionality statements in HCI.

Baby wearable technologies are becoming increasingly popular, particularly in early infancy. However, little research has been conducted to investigate how baby wearable technologies are adopted and used in parenting. This paper presents a two-week in-depth situated study with six mothers in their homes consisting of contextual entry and exit interviews, video recordings of "out-of-box" experiences, and a diary study. Using interpretative phenomenological analysis, participants' use and expectations of the baby wearable technology were examined. Use of the device directly impacted upon parents' knowledge production and anxiety, and influenced the perceived physicality and social factors of parenting. We frame these findings around sociological norms of the vulnerable child and responsible mother, as well as the notion of "lived informatics", where individuals' interaction with the technology influenced the perception, use and impact of the baby wearable on everyday parenting practices and familial relationships.
