Nanny Needed For My Children - Full-time / Part-time

Our son is 11 years old, he's pretty self sufficient. May need some help making food or snacks but otherwise he'll do his own thing. He does crafts with airplanes or rides his bike/go kart. We'd just like some more supervision since he's not ready to be home alone for hours yet. We do have a dog and cat, dog will need to be taken out once or twice. But he can just go out back.
