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

We are looking for a great nanny for my newborn son in Hydes. He will be 11 weeks old by the start date on September 21. The schedule will not be all 4 days of the week. It will vary from 2-3 days depending on when my mother in law has off of work. We would prefer a nanny who has experience with babies under 4 months old, has their own car, is comfortable with pets and who is CPR certified.
