My stepsister lives with my 80 year old father as his caretaker. However, she is fighting for her life, battling against cancer. My Dad is extremely high maintenance and she and her husband have to get up with him throughout the night. She won't call to try to find a night nurse or someone to even help during the day because she's afraid it will make him angry. How can we talk to my Dad, introduce a caretaker and get my stepsister a break. My Dad has alcohol-related dementia so he's not in his right mind. Thank you! We don't even know where to start to even find someone who would want to stay up with him all night.
