Babysitter Needed for my Children

We are looking for a great babysitter for our 2 daughters (2. 5 years old and 11 months) in Berwyn. Our 2. 5-year-old is in preschool Monday through Friday mornings so most often, watching our 11-month-old would be the primary responsibility however, there would be date night and other as- needed babysitting opportunities for both children. Experience with young children, CPR certified, and a non-smoker are all a must.
