Nanny Needed For My Children

We are looking for a great nanny for our 2-year-old little girl. Hours this summer would be minimal, a few times a month with increasing hours, 1-2 times/week, before my maternity leave in October. I will be having twins, and we are also looking for someone interested in watching all 3 of our children 1x weekly when I go back to work. We would prefer a nanny who does not smoke, who is comfortable with pets and who is CPR certified.
