Interventions that promote responsive feeding in early childhood have been shown to reduce obesity risks. However, interventions mostly target parent-child dyads without considering the complexities of implementing responsive feeding across multiple children within a family unit. This scoping review aims to assess the extent and nature of current literature examining feeding in the context of siblings. Six electronic databases were searched (APA PsycINFO, CINAHL, Embase, Medline, ProQuest Dissertations & Theses Global, and Scopus) for articles published up until November 25, 2021. Studies were included if they compared the use of parent feeding practices and/or styles for two or more siblings aged ≤18 years. Data were extracted from relevant studies and analysed using basic descriptive statistics. A total of 18 studies from North America (n = 12) and Europe (n = 6) were included, with the majority targeting children between 6 and 18 years of age (n = 12). All studies were cross-sectional, with most designed to test differences in parent-reported feeding practices for siblings, primarily restriction and/or pressure to eat, in relation to differences in their characteristics (n = 12). The studies provide some evidence that parents may modify certain feeding practices or styles for siblings in response to differences in their characteristics, such as weight status and eating behaviours. Future research should examine processes that underlie feeding decisions in the context of siblings, including the contexts and consequences of differential feeding, with particular focus on early childhood when feeding interventions may be most effective.
