Babysitter Needed for my Children

We're looking for a great nanny for 1 newborn and experience with newborns is a plus. It would be part-time, 10-3, five days a week (possibility for more hours depending on hourly rate). Some light tidying up would be part of our caregiver's responsibilities, only related to the newborn. Need to be comfortable with dogs as we have three. We also have a second child who is four and half but she goes to school. You won't be responsible for her but she might be around some days.
