Part Time Nanny For Our Second Boy! (Newborn)

We are a young family looking for someone to help with my newborn son. We have a vibrant and energetic 2-year-old boy-I mention him but he is in nursery school. This nanny would be helping with his brother, our new son who will be 4 months old in December. Responsibilities would be taking care of him/all things for him. Play with him while awake, go on walks, make food/bottles, wash bottle/dishes, laundry, clean/disinfect his toys, clean up etc. We are also hoping to having someone help out with light housework (vacuum, dishes) and simple cooking. I am a CPA with a strict tax season schedule that lightens up after April 15 and my husband works in NYC. Our schedules are flexible but we would love some structure with our kids. We are looking for a caretaker who has loving energy to keep up with our boys and who can grow with our family!
