The objective of this study is to examine Swedish child health clinics (Barnavårdscentralen – BVC) interpretation and evaluation of mother-infant relationships. The study’s empirical material is gathered using the vignette technique and the semi-structured interview technique. Analysis of the empirical material is undertaken using the thematic coding analysis technique. From the studies emprical material the following themes were identified: The roles of situational norm deviation and reoccurrence, the role of experience, routine & observation, the use of tools, straight forward open communication and trust and the child as an indicator for the mother’s wellbeing. The conclusion of this study is that BVC interprets and evaluates mother-infant relationships using a combination of experience, routine and observation to determine the degree of norm deviant behaviour present during routine BVC controls.
