Companion Care Needed

About who needs care: Grandma is wheelchair bound due to an amputation caused by diabetes. I have been able to take care of her for a few years but she is losing some mobility in her left shoulder, making it hard to sponge herself. I can cover all other aspects of her care, but she refuses to let me, grandson, give her a sponge bath. About the care needs: My grandmother is pretty agreeable and easygoing. She is a little hard of hearing though. So as long as you are patient, I'm sure she can get along with anyone. Services needed include: feeding, and bathing / dressing.
