Nanny Needed - Full-time / Part-time

We are looking for a great babysitter for 2 children in Littleton. A 6month old and almost 4yr old. We would prefer a babysitter who does not smoke, who is comfortable with pets (we have 2 dogs), and who is CPR certified. We need some from 08-5 p.m. We are looking for someone on Monday, 7/27 and the following Monday, 8/3. My husband does work from home on Mondays, but would be up in his office.
