@celia16 thank you for your reply. I am now listening to the 36 hour day and subscribed to the Teepa Youtube channel. I think Dad's still in denial a bit. It depends on the day for him, I think. I think he often believes that if she can just get sleep it'll be better? She has really good days sometimes but honestly now there are a string of bad days where she's like a robot and like she's seeing past us. She gets a lost look in her eyes that maybe only I see. Not sure if dad sees it. I think this is all really more than he wants to accept fully. They've been together like 60 years. I'm thinking about next steps but he is not there yet. I have to leave room for him to be ready. They are a unit and of course he doesn't want to see her upset or unhappy although he understands what is happening. It's all very tricky. I sense big events also shift things. A change happened with her dog a couple weeks ago that has impacted their daily schedule and all of a sudden a big shift in her cognition changed in the last two weeks.
