Nanny Needed For My Children - Full-time / Part-time

We are seeking a nanny/regular sitter for our 2. 5-year-old and our 3-4-month-old. Our schedules at the hospital are 7a-5p, and we have a 30 minute commute. So we would need someone willing to help us from 0630-1730 3-4x per week. Our 2. 5-year-old is nearly potty trained (occasional accidents) but is very smart and loves to play/engaging in activities. She loves to play outside. She loves to color, go on walks, do chalk, etc. Our children do not require any special or specific care.
