Babysitter Needed For 2 Children In Pittsburgh.

We are looking for a babysitter for 2 children in Pittsburgh. I work shift work so the schedule is variable and I would need you anywhere from 5-10 times per month. My number one quality I am looking for is reliability. You cannot call off except in dire circumstances or be uncommunicative. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who has their own car, who is comfortable with pets and who is CPR certified. I do not want my children to watch TV. I also want someone who is professional and energetic enough to play or supervise independent play.
