Nanny Needed For My Children In Kennewick.

I am currently looking for a sitter for my two kids, E 14 years old & E 7 years old. The hours I'm looking for are Wednesday 1:40 p.m. to approx 6:30 p.m. Thursday 2:50 p.m. to approx 6:30 p.m. Friday 2:50 p.m. to approx 6:30 p.m. And on those days where there is no school, start time would most likely be 10 a.m. but could possibly be noon. I'm looking for someone to come to my home. The kids do get dropped off by the bus. But someone with a license/car/registration is important as I am looking for someone more permanent, into the summer. I'm looking for someone that is fun & likes to be involved w/ the kids (I'm not wanting to pay someone to sit on the couch), patient, nurturing, reliable, & punctual. Must be a non smoker. And I do not want any other kids coming with you. A big plus if you have experience w/ Down Syndrome.
