Research about siblings where one has a disability has historically focused on the psychological outcomes of siblings of people with disabilities and has very rarely asked people with disabilities about their sibling relationships. This research focus represents the common individualizing approach and under-representation of people with disabilities that disability studies has argued against. Tracing the history of research about siblings and disability through de/institutionalization and towards current broader theories in disability studies, this article suggests that a range of disability studies perspectives can usefully de-individualize and expand research about siblings where one has a disability. Through examples of how materialist, feminist and inclusive perspectives can be applied to open up research about siblings and disability, the article argues that viewing siblinghood through the range of disability studies perspectives has the potential to expand this research field and represent new facets of siblings’ identities and lives together
