Babysitter Needed For 2 Children In Annandale.

I am seeking a great sitter for 2 children in Annandale. I would prefer someone who could help out with guiding the children in light housekeeping/chores; monitoring outside play for safety, prepare/provide meals as needed. I need someone with their own car, who does not smoke and preferably has/is currently pursuing a college degree in child development, education or a related area. I also have two teens who may/may not be home but are self sufficient and dont need oversight.
