Babysitter - Full-time / Part-time

We are looking for a great nanny for 1 child in Greenbelt for 4 hours in the morning to afternoon while mother works from home a few days a week. We would prefer someone who could help out with light housekeeping centered around the baby. We would prefer a nanny who has their own car, who does not smoke and who is comfortable with pets as we have a dog, cat and bird.
