Babysitter Needed - Full-time / Part-time

We are a Swedish/Brazilian family relocating to NYC from Stockholm and need a nanny for our 2-year-old twins, with flexibility to work mornings, afternoons, evenings, and sometimes overnight. This could potentially be a live-in nanny position. Both kids will attend preschool, so daytime hours are free or can be used for light household work. We would prefer a Brazilian nanny so our kids can continue learning Portuguese. We live in Tribeca.
