Companion Care Needed For My Mother In Des Moines

About who needs care: My mom is 82 years old and she has moderate Alzheimer's. She is able to dress herself and go to the bathroom by herself, but she needs someone for companionship and just sit with her for 5 hours during the day while my dad (her primary caregiver) gets a break. She is very easy and requires no actual care, just companionship. About the care needs: Someone outgoing would be good because she is shy and sort of needs someone to bring her out of her shell. She really just likes to watch TV but does like to have conversation. Services needed include: meal preparation, errands / shopping, light housekeeping, and companionship.
