Based on the living experiences of 11 primary caregivers, this paper finds that gender is crucial for adult children to serve as primary caregivers to their elderly parents. First, male and female adult children have different views of their roles as primary caregivers. According to their views, sons are fulfilling the expectations of their elderly parents in providing care to them, whereas daughters are trying their best to provide their elderly parents with quality care. Secondly, although the feminization of caregiving tasks makes the female children as “ideal” caregivers, the taboo on “gender” and “sexualities” still offers a challenge to female children caregivers. Thirdly, the possible ways to release the boundary on gendered family caregiving are also discussed in the interpretations of primary caregivers.
