Nanny Needed For My Children - Full-time / Part-time

We need help Mon-Fri from 3:15 - 6:45 p.m. Responsibilities include: watch the kids after they get home (we live 2 min away by walk from school and kids walk home by themselves), supervise outdoor play if whether permits, prepare dinner for the family, and some light tidying up. We have a cat at home. We are looking for someone with experience caring for children, warm and responsible. 1-2 references required.
