Companion Care Needed

We're looking for a companion/caregiver for our mother who has short-term memory issues and is beginning to show signs of cognitive decline. She lives with her sister, who handles cooking and groceries. We're looking for approximately three 1-hour visits per week. The main responsibilities would be medication reminders, prompting with showering and personal hygiene, helping with her hearing aids, companionship, and letting the family know if anything seems different or concerning.
