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

We are looking for a loving nanny for our son who is currently 5 months old. I go back to work this coming week. We would prefer a nanny who has their own car, who does not smoke and who is CPR certified. My husband may be at home on the days we need care, as his schedule changes from week to week. The extra care is much appreciated. We are willing to have someone with minimal experience, who can learn on the job.
