Questions to consider include: How will the senior cope living with others especially if there are children in the home with various schedules, activity and needs? Will living in your home impact their privacy and independence? Are you close to their current social network so they can still visit with friends? How demanding is the senior? Will other family members be required to provide care? How will moving the senior into your home impact your job and/or your relationship with your spouse/children? Are there services in your community that can assist with any care if it is required now or in the future? Can you afford the extra person? Will they contribute money? If they do, will this create problems with other family members?
Inter-generational families living under one roof can be extremely rewarding for all family members involved however, for some families adding additional people to your nuclear family can be stressful and can create problems. For those struggling with a decision such as this, do keep in mind that caregiving can be difficult for even the most cohesive of families and if for whatever reason it is not feasible to move your elderly relative into your home, it's important to recognize that sometimes the best decision for all involved might be to let others provide care - even if it means relocating the person to a seniors home of some sort. It cannot and should not be viewed as any sort of failure or as a reflection of how one feels about the person. Sometimes, it is clearly the best move for everyone.
