My husband may be coming home....His daughters want to have CNAs in to watch him alongside of their limited supervision. Is there a contract or something that you have these people sign before they work for you? My husband is over 400 lbs and has no bladder or bowel control. Vas dementia and intermittent delirium...Is it wise to even let him in the home? They have ordered expensive equipment, so that will be a good thing....He is unable to walk, can stand for transfer to chair....Any thoughts or help! It's hard finding a skilled nursing facility to take him due to weight....Thanks ahead of time!
