Nanny/Mothers Helper

We are looking for someone to provide part-time nanny or mothers helper support to our family once our 3rd child arrives this October. Our oldest attends school full-time and will not need care. We are hoping to keep our middle child (age 2) home once the baby arrives to reduce the risk of illness. My husband and I both work from home and will be available as needed, but primary responsibilities will start with our 2-year-old and gradually introduce the newborn. We would love someone that could assist with light housekeeping (laundry, meal prep, etc.) as well.
