Nanny Needed For My Children In Portland.

I have a 2-year-old girl and 4-year-old boy. My son is a great kid, but has autism and so requires someone who knows how to engage with neurologically atypical children. I work at night during the week, and need someone that can bathe them, put them to bed, maybe give them a snack, read stories etc. There are also two older teenagers in the house who are good with the kids, but I need a responsible, reliable adult to help out also.
