Babysitter - Full-time / Part-time

Planning ahead to my return to work and looking to find a part-time nanny (approx. 25-30 hours/week) for my soon to arrive infant son. Must be comfortable with mom working from home, have extensive experience with infant care and developmentally appropriate activities and needs. Looking for someone to grow with our family and who is interested in a long-term relationship. Ideal candidate should have their own transportation, non-smoking, and some flexibility as needed with schedule (we will give guaranteed hours).
