Babysitter Needed for my Children - Now Hiring

We are looking for a part-time nanny to help with childcare during working hours for mom, who works part-time as a PA. The schedule is not consistent week to week and will have sigificant variability. We have three kids, the oldest is in 2nd grade and goes to school every day, middle is in a half-day 4k program and the youngest is an (almost) 2-year-old who is home every day.
