As NYC families, most of us are intimately familiar with the wealth of opportunity that is available for our children here in the city. By five years old, many children have been exposed to the finest art, music, theater, museums. Even our children's palates have experienced more than many children growing up in other parts of the country - sushi, lox, exotic cuisine from around the world, all are accessible and at least part of our children's vocabulary, if not exactly to their taste. Because we live in a city that truly has the finest of everything, it's sometimes difficult to decide what, as well as how many of the various activities, classes and experiences are appropriate for our children.
