Nanny Needed For 1 Child In Port Saint Lucie.

We are looking for a great nanny/sitter for our 5-month-old in Port Saint Lucie. Our schedules vary each week for work. My husband is a firefighter that also has an on call position with their sheriff's office and I'm a flight attendant that works minimum hours, but we will have some overlaps with our schedules once we're both back at work. There could be times when I'm at home and just need to sleep for a few hours after working all night. We would prefer a nanny/sitter who has their own car, who does not smoke, who is comfortable with cats and who is CPR certified.
