Thank you ((Bebop, Daniella, Muffy, NWTR and 50guy))
50guy, I really like your idea. Her only break is going out to the pharmacy or picking her daughter up from school, but even then she's in a hurry to get home. She doesn't like to lean too much on her mother because her mother also cares for her ailing grandmother. Poor mom has to work, care for an ailing mother in her home AND her ailing son-in-law in her daughter's home.
I think a service as you suggested would be a God send to caregivers like my friend. She's still young and has so much life in her. She could use a few days out on a beach somewhere with her girlfriends, umbrella drink in hand.
