Babysitter Needed for my Children - Now Hiring

We currently have an amazing part-time nanny that is heading back to work for the school year. We would love someone to watch our 3 kids 1-3 times per week (2 in part-time preschool + 1 infant). I do not work, so days and times can be pretty flexible. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets (we have 1 dog), and who is CPR certified.
