My Mom is 82 and needs an overnight sitter to assist her to the bathroom when she gets up in the middle of the night. I have a live-in caregiver that takes care of her during the day. The caregiver lives upstairs in a split level home. The overnight sitter will watch my mom from 8pm to 6am, 4-5 days a week. We can talk through the schedule if you are interested. Your job will be to sleep downstairs on the couch or cot. I have a bed alarm that sounds when my Mom gets up. Your role is to assist her to the bathroom and bring her back to bed.
If you have any issues you can buzz the caregiver that is living upstairs. The pay is a flat $100 per night.
