Companion Care Needed

About who needs care: She has Alzheimers. She is mobile and pretty high functioning. She can feed herself, but she is unable to go to the bathroom herself and wears adult diapers. About the care needs: Companionship, so my father can have some time away from the house. Someone who can assist her with bathroom duties such as going to the bathroom and changing her if needed. We would prefer a female because we think she would do better with one. Services needed include: companionship, feeding, and bathing / dressing.
