Hi, Julie! Welcome to the forum!
You sound like a wonderful caregiver, both conscientious and compassionate. You probably already know far more than I, so I hesitate to offer advice. But I have had PD now for 16 years and am a member of this forum and one in the US. One principle I have heard repeatedly is that those of us with Parkinsons would rather do what we can for ourselves and get assistance only when we ask for it. Somehow, we feel diminished or insulted when someone just assumes that we will need help.
You will get much more valuable information from others on this forum, I'm sure. It has been illuminating for me, I know.
Best wishes -- J
