Dealing with possible anosognosia and FTD

We have been living with my MIL for about 6 months. She was diagnosed with FTD approximately 5 years ago. I could not say definitively what stage she is at as my SIL managed most of her care previously as she lived closest but was not able to move her into her home. The decision to have her move in with us was prompted by increasing signs that she was no longer able to manage things like driving and cooking for herself. After her initial diagnosis she was aware of the diagnosis and over the years had questions and anxiety about what that meant, but I have noticed in the time she has been living with us that awareness is gone. It's not that she denies having dementia, it's just not discussed, but she does not seem aware or acknowledge the need for support and when the dementia diagnosis does come up, like at the doctor's office, she does not understand what that means.

The difficulty we are experiencing is the time my husband and I are out of the house. Initially we thought she might be ok for a few hours while we both work as our work schedules only overlapped one day of the week, but after a fall she had while out on a walk without our knowledge as well as some other questionable decision making while we were gone, we realize constant supervision is probably best at this point. We located an Adult Daycare in our area, took a tour, took her to visit it, and decided to sign up for the minimum required days, which is 2. While we have some kinks to work out as far as how long she should be there, and what time of day (definitely not too early as waking her up before 8am is definitely courting disaster) the two days she has gone so far have been met with a lot of resistance. She believes she does not need to be there and does not need any assistance, and I suspect anosognosia is the cause. To be fair, to the casual observer, you would not know she has dementia. But she relies very heavily on the routine we have set up in the home, is beginning to have difficulty bathing (still does it but is likely just going through the motions most times as I do need to wash her hair for her every few days), struggles to think of ways to occupy herself without direction, cannot follow a series of directions, consistently forgets where things are in the house despite things being labeled, and I'm not convinced would remember to eat meals without being directed. She can fix a bowl of cereal on her own and regularly assists me in meal prep at dinner time as long as I keep the instructions simple, but I have had to start prompting her to eat something in the afternoons as well as preparing a lunch as she was not doing so herself.

My question is how have you all delt with these kinds of transitions. The move into our house was not exactly met without resistance, but once she was here it did not take long for her to settle in. The Senior Center is a whole other level of resistance and I'm at a loss on how to proceed as I don't think she is aware that she has a problem, or at the very least, she does not believe it is bad enough that she cannot be left unsupervised. The care center has seniors of all abilities, some nonverbal, some recovering from strokes, but there are definitely those who would be considered peers as far as ability. However, all she is focused on is that she does not need help like "those others do" and does not recall the interactions she has that are positive. I am concerned that this is going to just become a point of contention and an argument every morning we need her to go to "that place" despite us trying to put a positive spin on it. Do we just give in and try and seek alternate care that will likely be met with the same resistance? Do we dig in and just plow through and hope she adapts?
