National policies such as Better Outcomes, Brighter Futures (2015), First 5 – A Whole of Government Strategy for Parents and Babies (2019) and Supporting Parents: A National Model of Parenting Support Services (2022), recognise the importance of, and reflect a strong and enduring commitment to, supporting early childhood development and wellbeing through the provision of accessible, high quality and evidence-led supports. For instance, a key goal of ‘First 5’ is to develop strong and supportive families and communities, including a commitment to the development of universal parenting supports (also reiterated in the National Model of Parenting Support Services) and, importantly, in the context of the current study, an evidence-led approach to home visiting services across a continuum of need (Department of Children, Equality, Disability, Integration and Youth (DCEDIY), 2022). Indeed, a wealth of both national and international evidence indicates that the home environment, and therefore services provided in the home, provide a crucially important context, and support, for healthy child development and wellbeing (e.g. Bradley & Corwyn, 2008).
