Part- time Nanny for 2 school age children for over night care - Full-time / Part-time

I'm a new physician entering residency, and my husband is an ER nurse. We have 2 young kids still at home that are 13 and 6 yrs old. We also have a sweet golden retriever, a cat and a rabbit. My husband works nights so we are looking for someone that kind, caring, trustworthy and reliable to stay with our children over night when our work schedules over lap. We live in the old mill subdivision in Geismar.
