Babysitter Needed for my Children - Now Hiring

We are looking for a great nanny for 2 children in Porter Ranch. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke, who is CPR certified and who knows how to multitask since I do have 2 toddlers. Comfortable being very active with them. I am a nurse and my schedule does vary so not every week will the days of work be consistent.
