Overnight Companion Care Needed For Our Father

Looking for someone to sit with our dad overnight to keep him safe from falling when he gets up in the night to use the bathroom. He's currently living in assisted care and they only check on him every two hours. He has fallen a lot recently. He has alzheimers and Parkinson's. Hours are 9:00 p.m. - 9:00 a.m. and available shifts are 7 days a week. Looking for someone to work at least 3 nights a week.
