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

We are looking for part time care over the summer for our 3 kids- 2 toddler boys and a baby girl. Potential to continue into the fall depending on availability. 1-2 days a week, about 4 hours a day. 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 and who is CPR certified.
