Babysitter Needed

We are looking for a great nanny for 3 children in Sewickley. We have a 5-year-old and 1. 5-year-old twins. My wife works 10-15 hrs per week on variable days and so our need would likely be either all day on Tue/Thurs or pickup from kindergarten/daycare on M/W/F around 1 p.m. 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 and who is CPR certified.
