Nanny Needed

I am looking for an occasional babysitter for weekdays when my part time nanny is unavailable, and on occasional weekends (early evenings). My work schedule is different every week, so no two will be the same. During the day, my 4-year-old is in school; so most of the daytime hours will be with the 1-year-old. To guarantee a couple days a week, I am open to house manager tasks on days where I do not necessarily need child care. This could include folding and putting away laundry, dishes, cleaning up after the kids, organizing toys etc.
