Caring For Aging Parents Support Group
Caring for aging parents can be a difficul time as we become the caretakers for our parents. This broad responsibility can encompass such services as assisted living, adult day care, long term care, nursing homes, hospice care, and in-home care. Whether you have just started caring for your parents or just need a place to talk, we're here.

Gentle hugs, these things can be very hard emotionally.

My wife and I finally got POAs so our children can step in when necessary. Perhaps if you do the same you can use that to help convince your mom of just how necessary it is.
