Babysitter Needed for my Children

We're a family of three on the East Side looking for an active, calm, warm, playful, flexible part-time nanny for our almost-5-year-old son. He's silly, very active, curious and clever; he loves books, sports, biking, art, science experiments, playgrounds, Magna-Tiles and cooking. We're a low-screen family and love adventures, local events and the arts. Our schedule varies week to week due to Dad's job as a corporate pilot, so flexibility is key. We'd primarily love help with school pickup, afternoon activities, and dinner prep, plus some date nights and additional hours as needed. French or Polish language skills would be an amazing bonus, but not at all required!
