Ms. Peaches

I work for an elderly couple in the area. I care for Ms. Peaches who has Alzhiemer's, while her husband does errands, goes to excercise, or goes out to breakfast with friends. I have been working with Ms. Peaches for a year and when I started she was able to help do laundry and make her lunch. She's had periods of anxiety, aggression and days where she wanders the house opening and closing the blinds. But I have noticed in the last 2 weeks that she seems less cognitively aware of her surroundings and she doesn't say "hello" to me in the mornings any more.
That makes me sad.
The family wants to keep her at home. I understand wanting to keep their loved ones near. But I see Ms. Peaches just sitting in her chair watching TV, not being engaged. I have tried my best to engage her in conversation, we look through her new magazines and we made a memory book.
The daughter called the other day to "vent" about her dad. He's waking Ms.Peaches up at 6:30 every morning to get her ready for the day because that's what she did before she became ill. I'm sure the husband will broch this subject with me at some point. I've been mulling over in my mind how this conversation will go. What direction will this conversation take? Why does he feel that she needs to keep the same schedule? Does he feel that letting her sleep is giving in to the disease? I'm anxious about this conversation but I feel that I'm prepared to guide him through whatever decision he makes. Thanks to my "therapuetic use of self".
