Companion Care Needed

About who needs care: I need a female to guide & supervise a weekly shower time. About the care needs: My 93 yr. old mother has dementia. She fell in April and spent 6 days in the hospital. Followed by two and a half weeks in a rehab facility. Bathing has always been an issue for us. She acts insulted and angry when I tell her she needs to bathe. Today (6/30) is the last day of her doctor ordered home health care services. She is quite cooperative when someone other than me tells her it's time to bathe. Services needed include: feeding, and bathing / dressing.
