Babysitter Needed for my Children - Full-time / Part-time

I'm looking for a great part-time nanny for 1 newborn, expected due date Oct. 17. Likely will be needed between 9AM-1 p.m. a few times a week. Occasionally on weekends in the evening. We would prefer someone who could help out with light housekeeping. Please be comfortable with two dogs that are very nice. Must have a lot of experience with newborns and any certifications are a plus.
