Sorry to hear you're having such trouble with the caregiver, Elise! I've been lucky that the one I hired for mom is very dependable as well as willing to do just about anything we ask of her, but she's a "private hire" and not through any agency, so she knew what I needed her to be willing to do before I hired her.
Never have had much luck with the agency caregivers....of course they don't pay them very well and the "good ones" are overworked
Sure hope Max perks up for you! I know how worrying it is when there's just something "off" and we can't really put our fingers on what it is!
