Babysitter Needed for my Children - Full-time / Part-time

We are looking for a reliable, caring occasional babysitter for our 28-month-old daughter. We have a regular nanny, but we're looking for a trusted backup caregiver for when she's unavailable, as well as occasional evening events. Our first need is Saturday, September 5, from approximately 5:30 p.m. to 9:30 p.m. Before then, we'd like to schedule a paid 2-hour meet-and-greet/trial visit so everyone can get comfortable. We're looking for someone who has experience with toddlers, is dependable, engaging, and comfortable with an evening routine. CPR/First Aid certification is preferred. If it's a great fit, we'd love to build an ongoing relationship for future babysitting needs.
