English speaking nanny/ teacher

We are looking for an english speaking person to spend time (playing, learning, going to the playground) with our children (2 and 4-year-old girls). We live in Warsaw in Sadyba. We offer flexible working hours - it can be full-time or part-time job. I work from home, so I'm there if needed. We don't expect cooking or cleaning. We are looking for a warm person who likes to spend time with children.
