Nanny Needed For 1 Child In Los Angeles

My wife and I have a 3-year-old daughter. She's in school (M-F 8:30-12:45 pm). Since my wife works at the hospital once weekly (7am-7pm), we need a regular sitter/nanny for that day (630am-8pm). We also would like the option to have a week/weekend night available for date night (3-4 hours). Our current sitter who has been with us for the last two years just went back to school full time. Our daughter will need assistance with: clothing, preparing meals (usually just warming up in oven), walk to preschool (1/4 mile down road), pick up from preschool, getting her down for a nap, dinner, getting ready for bed (brushing teeth), cleaning (picking up toys or mess made during that day; washing dishes made dirty from that day) Both parents work. Husband works daily. Wife works once weekly (12-hour shift as described). CPR certification required
