Babysitter Needed for my Children

We have two girls (1. 5 and 3. 5 years old). We are looking for a nanny for Wednesdays and Fridays. On Wednesday, our older child may need to be picked up occasionally (preschool within walking distance). Both girls need to be watched on Fridays. Looking for someone to start later this summer or early fall. Hours needed are around 8 AM-6 p.m. We have a cat and two small dogs at home so must be comfortable with animals.
