Afternoon Nanny For 3 Children In Atlanta

We are looking for a great part time nanny for our 3 children in Atlanta. The job would focus on picking up kids from school/bus and taking care of them in the afternoon & evenings, including taking them to after school activities, helping prepare dinners, and light house work as time allows (kids laundry, grocery shopping and errands). Additionally, on some evenings - we will need help through bedtime. We expect to need 20-25 hours a week. We would prefer a nanny who does not smoke, who is comfortable with pets (we have a 15 lb dog) and who is CPR certified.
