I was able to find 2 songs called CHILDREN OF THE WIND.

One of them was written by David Clayton-Thomas and recorded by Blood, Sweat & Tears. It's on their album "What Goes Up: The Best of Blood, Sweat & Tears," 1995.

Another was written by Stephen Schwartz (words) and Charles Strouse (music) for the musical play "Rags." It has been recorded by Judi Connelli and Suzanne Johnston; Marie Michuda; and Ann Arvia.

I just listened to some samples. Neither of them sounds like the kind of song kids would like to sing.
