Babysitter Needed for my Children - Full-time / Part-time

We are looking for a great nanny for 2 children in Mansfield. We have rotating schedules so some weeks we need more hours than others. We do know our schedule in advance and can provide exactly what hours/days are needed ahead of time. We may only need afternoon pickup, or may need full days depending on the week. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets (we have 2 large but friendly dogs) and who is CPR certified.
