Siblings of individuals with intellectual and developmental disabilities (IDD) are likely to become caregivers for their brothers and sisters. The expectations of and experiences with caregiving, however, may be different. In this study, using focus groups, we compared the perspectives of siblings who were current caregivers (n = 25) to siblings who anticipated being caregivers (n = 17). Responses were compared and contrasted across four areas: caregiving responsibilities, rewards, challenges, and opinions toward being paid as a caregiver. Both caregiver groups were knowledgeable about and invested in their brothers and sisters. Also, they both reported that they enjoyed bonding with their brothers and sisters. Challenges, for current caregivers, related to understanding and navigating the service system. In contrast, anticipated caregivers were concerned about planning for the future. Mixed viewpoints were expressed about receiving pay for providing care although a greater number of current caregivers were receptive to it as a means to supporting their own families.
