Babysitter Needed - Full-time / Part-time

We are looking for a great nanny for our 4-month-old baby in Orange, CT. The care would focus on our baby 1x/week (every Wednesday) starting in November going until August of next year from 7:30AM-4:30 p.m. We do also have a 5-year-old and a 3-year-old, but they will be at school, so the main focus is on our baby. We do also have a golden retriever, so being comfortable with a dog is a must - he has an e-fence, so would just need to be let outside and back in on days when we are not home. We would prefer a nanny who has experience with infants, does not smoke, who is comfortable with pets and who is CPR/First certified.
