Recent research has highlighted the increasing trends in newborn and very young children entering child welfare processes and care proceedings in a number of countries. Furthermore, differential responses to risk within young families across different geographical locations and communities in the same child protection system have been found. Safe care arrangements for newborn babies may include placement with kinship carers or with foster carers not previously known to the family. The distinctive needs of the increasing population of infants in the care system are only beginning to be fully recognized. The short-and long-term impact of contested infant removals on birth mothers has been powerfully highlighted, although the impact on fathers remains under-reported. There has been limited research evidence available on how decisions about the care arrangements for newborn babies are reached. In this paper, the author draws on data from an ethnographic study of pre-birth child protection in order to explore how social workers understand and frame risk to infants when assessing families during pregnancy. Data from interviews with practitioners reveal the extent to which their conceptualizations of and anxiety about risks to unborn babies shape plans for the future care of infants.

The research took place within an urban Scottish setting and focused on the activities of social work practitioners and their interactions with expectant parents. Unborn babies lack legal personhood in Scotland, meaning any legal action must wait until the baby has been born. However, child protection processes may be initiated during the pregnancy, thereby providing a forum for important decisions about the future care of the baby. The choices made by parents during the pregnancy may also be taken into account in the grounds for any legal steps later enacted. Increasing numbers of newborn babies and infants find themselves subject to care proceedings and separation from birth family in Scotland (Scottish Government, 2019; Woods & Henderson, 2018), a trend that has been noted in other countries with child protection systems focusing on immediate risk (Broadhurst et al.,
