Childcare Needed

We are looking for a great babysitter for 2 children in Chadds Ford. We would prefer a babysitter who has their own car, who does not smoke and who is comfortable with pets. Our youngest will need to be picked up from PreK (10 minutes from house) and other child would get off the bus an hour later. We only need someone for about 2-3 hours a day during the week.
