Nanny Needed For My Children

Hello! I am looking for someone to help me in the afternoons and early evenings as I manage my kids schedules. I have 4 kids aging from 16-9. My main need is pick up and drop offs from school/activities - and then sometimes staying at our house with one or two of the kids who need to be supervised. Our schedules are constantly changing - I prefer to be with my kids myself, but the schedule does not allow it. Sometimes I may be home cooking dinner, and I just need someone to take kids to their sports.
