Nanny Needed For 2 Babies In Sterling/Dulles

We are looking for a great nanny for 1 child in Sterling/Dulles. We're also expecting another baby boy in late March, but the baby will be under our care until 4 months old. At that point, we can adjust the hourly rate to reflect 2 boys! 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 and who is comfortable with pets.
