Childcare Needed - Full-time / Part-time

We are looking for a great part time nanny (M-F for 4 hours a day) for an infant (born in May). We are located in Ann Arbor and would prefer a nanny who does not smoke, is fully vaccinated, who is comfortable with pets (a cat and a dog) and who is CPR certified. We prefer mid morning to early afternoon each week day but are flexible.
