Is classical music kids music?

Some of it is wonderful to work with kids (I taught it for many years). Pieces such as the suite form Tchaikovsky's "Nutcracker", and Saint-Saens "Carnival of the Animals" are two good examples.

Edit:

Not necessarily. Classical music is for everyone. As for kids playing classical music, pieces by Chopin, for example, might not be the best choice because of the emotions associated with it (somewhat depressed, heartbroken, etc). Beethoven's 'Moonlight' Sonata also deals with 'adult' emotions, so it also might not be considered 'children's music.' Although kids can play those types of pieces, it would be hard for them to genuinely be able to feel those emotions (assuming their life isn't a total tragedy).
