Your mother is fortunate to have you in her life and it is wonderful that she is going to be living with you! It is great that shie is healthy and it sounds that she is getting around ok.
Although I don't know any more details about your or your mother's situation, my own thinking is that you might want to find someone who could be a "companion" to your mother while you are away. This is a trusted person(s) who can "be there" for your mother to ensure that she is ok and who would use common sense in dealing with your mother and be authorized to do what is necessary should an emergency arise..Perhaps there is someone at your church or temple who might be willing to help out during this time? Is there a young college-age person in your circle who might be able to help out in this way--or a neighbor? Maybe there is one of your mother's "buddies" from where she lived before she came to live with you who might like to have a "mini-vacation" at your place with your mother while you are away? You could pay these people for their help to be a companion during the time you are away. These are just ideas--there indeed may be better options in your community. Since you don't say that your mother is incapacitated, needs medical help, or has a mjor cognitive problem, I am thinking that there are better options than temporary re-location in a nursing home.
It's great that you are getting away--being a family caregiver is a big job! This is true whether you are a "live with your your elderly mother" caregiver or whether you are caring from "long-distance." If you want other ideas about options and resources for what you are needing --what you are describing is usually referred to "respite" services-- I would highly recommend that you contact the Area Agency on Aging serving your county. This group can help you get some answers to your current question and would be a great source of help if your mothers situation becomes more challenging.
Area Agencies on Aging know how to listen to seniors and their family members and can provide guidance and advice that may be of great help to you and your mother.You can call 1-800-677-1116 toll free to find out the phone number of the local Area Agency on Aging office. When you call the Area Agency office, ask for the person who provides "Help for Family Caregivers." If you make this call, I am confident that you will find friendly and helpful people.
It's important to know that Area Agencies on Aging aren't selling a particular service, "insurance plan" or other product. The information you'll receive will come from people who talk to seniors and families every day and you will be provided with objective information about options.
When you talk with the folks at the Area Agency on Aging ---you should ask about services that might be available to you as a family caregiver. Of course, ask about available in-home services that may be needed for your mother now or in the future. These services are for the seniors' benefit as well as for family caregivers like you. Area Agences on aging also have information about other residential and nursing home options that are available..
Sometimes in-home services are available on a "cost share" basis and the costs of services are based on the seniors' income or assets. If your mother is very low income and has significant needs that puts her at risk of going to a nursing facility, you should ask the Area Agency on Aging folks if the state where your mother lives has something called a "Medicaid waiver." If your state has a Medicaid program that covers individuals with disabilities and or frail elders, there may be Medicaid funding to pay toward in-home care. State governments are coming to realize the importance of having in-home services--with the involvement and support of family caregivers--as an option in the funding of services needed by frail older Americans.
Finding a attorney who specializes in public benefit or family law might also be advisable. Your mother,.you and other family members will want to figure out arrangements for "powers of attorney" and have a "living will" in place --and throughly discussed -- before an emergency arises. Your Area Agency on Aging would have information about these matters and would know how to connect you with professionals who specialize in this. Usually the Area Agency has "boiler plate" versions of these types of documents to get conversations in this sensitive area started. If your mother is low-income, the Area Agency may know of legal services that can help deal with these kinds of legal matters..
If you call the Area Agency on Aging and like the help that you receive, let your county elected officials know and tell your members of Congress. Area Agencies don't have big budgets--in fact appropriations for most services funded under the Older Americans Act have not increased significantly in 25 years! You will not be charged for the information you receive, however, any financial contribution you or your mother might make for the time and assistance devoted to your situation would be very welcomed--and would go toward helping more of your older friends and neighbors and their caregivers.
I hope this helps and that you have a great time on your vacation. Thanks for a great question and for caring! Best wishes and good luck to you and your mother!
