Is there a list of Caregiver things to do?

You say that your mom has "damaged" her previous caregivers health, and so now you want to take her on and damage your health as well??? Really??? Stop and think about that for a minute(or 2). You also say that she is "very high maintenance(mentally, emotionally and physically)". Do you really think that you are prepared to deal with all that? Just because you are the "only child", doesn't mean that you are required to care for your mom in your home. You can still care for her from afar, by finding the appropriate facility for her to now be placed in, in Florida, where she will have people that are trained "caregivers" look after her, and where their health won't be damaged, because she will have many people looking after her, instead of just one, you. I hope and pray that you will think long and hard before making the decision to move mom to your home, because once she's there, you become her 24/7 caregiver, and life as you once knew it, is over. There is nothing easy about that, as her sister can now attest to, so please do what's best for you first, then your mom. Good luck.

If mom is competent there is nothing you can do to force a move. See if there is a geriatric care manager in her area that would help coordinate everything for her.
