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

Hi ! For now we are just looking for someone as needed for our 1-year-old mostly, we do also have a 12-year-old girl but she is pretty self sufficient. Im a stay at home mom just needing some relief sometimes for a few hours to run errands or get things done. My husband works 48 hour shifts so its just me a lot of the time. Would prefer a non-smoker, we have 2 cats, and someone who knows basic first aid. Thanks!
