Glad I thought of something useful!
My mother is going to Las Vegas next weekend with some friends, and other friends (from the Navy) are going to stay with Dad, take him to the country club, play golf, and so on. She’s looking at getting a home-care aide for other times when she wants to go somewhere. She said the ones with the employment agency work 4-hour shifts, so she could get someone from 5:00 - 9:00 p.m. to make sure Dad ate, took his medicine, turned everything off, locked up, and so on. Then he could go to bed and be fine until morning.
It sounds like your mother is doing what she needs to do in order to care for your dad like he needs. (If that makes sense...)
I’ll wave at her as she flies over, since we’re right in the flight path for McCarran! LOL! Coming or going!
Does your dad have a “med-alert” (bracelet or necklace) for those times he’s alone? That would be a good investment, if he’s alone in the evenings, even once in a while.
Your mother should be able to get the information from the 2008 Medicare book.
