Outside our house there is corner of the backyard that we never quite got around to finishing. It has been a paradise for kids. The children have made secret hideouts, schools, and castles out of old cinderblocks, wood, fence posts, and whatever else they found lying around. One more window all of us need is personal space. Most of us have a hard time trying new things if we are watched too closely.
Children are the same way.
While they need lots of valuable input and supervision, they also need room to try things on their own. Several years ago Andrea and Peter made a cassette tape of a story they created themselves. They experimented to find suitable sound effects on the synthesizer and disguised their voices to represent different characters. We don't drink tea. Several years ago I had the impression that someday our family would sing in Russia.
