Background: Siblings often share in the care of parents with dementia, but little is known about how care is shared. Research suggests that in comparison with their brothers, sisters provide the majority of care to a parent with dementia and this can contribute to the sisters experiencing poorer health outcomes. There is limited knowledge about how to guide siblings who share in the care of a parent with dementia. Aim: Our qualitative descriptive study sought to explore the experiences of adult daughters sharing care responsibilities with their siblings.
