My 87 year old Mother is caregiver for my 97 year old Father. They still live in their home. My Father wakes up most nights between midnight and 2am, insisting it is morning and wanting my Mother to help him take a shower, dress and prepare his breakfast. If she tries to convince him it is the middle of the night he becomes agitated and belligerent. He says mean things to her. She is resistant to putting him a care facility. She has hired part-time care givers for a few hours two days a week and 4 nights a week. This is not enough and my siblings and I are very concerned about her welfare. What are our options?
