Babysitter Needed for my Children

We are looking for a great nanny for our 18-month-old in our home in the Highland Park area of Pittsburgh. We are looking for someone three days a week, 7 hour days (baby sleeps 2. 5 of those hours). We would love someone who will take her to the park and library regularly (both are about 10-12 minute walk from our home). We would prefer someone who could help out with light housekeeping (just light dishes, cleaning up after play time, folding baby laundry during her long nap). We would prefer a nanny who does not smoke, who is comfortable with pets (one cat) and who is CPR certified. Happy to answer any questions!
