Babysitter - Full-time / Part-time

We are looking for a great nanny for our 3 children. It would sometimes be just 1 or 2 of our kids, less commonly 3 kids. We would prefer someone who could help out with light housekeeping (or at least tidy up after play time/meals) but play and safety are the priority. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with our dogs in the house, and who is CPR certified. Need one full day per week, and one half day. May be able to change the day of the week if needed, currently looking for half day Wednesday and full day Thursday . Thank you!
