Nanny Needed For 1, Soon To Be 2 Children In Brooklyn

We are looking for someone to help us 3x in the afternoons (roughly 12-5 or so, likely MWF) through late May, with the potential to switch to 5x a week. We are looking for someone primarily for our son, who will be 2 years old in early April. I am pregnant and expecting in late May, so we may need additional help at that point. We live on a 4th floor walk-up in Park Slope, and our son is pretty big (35-40 lbs). Our son attends a program in Prospect Park in the morning, so we would need help with pickup to our apartment. He sleeps from 1ish-3ish most days so there is a good portion of nap time during the afternoon. Finally, we are looking for someone willing to do light meal prep and cleaning (ie, making PBJs, turning over the laundry). Thanks!
