We heard our nonverbal autistic son saying or singing something repeatedly every day and we thought it was meaningless sounds. UNTIL one day (this morning) we really listened and figured out he was SINGING Katy Perry's "Roar" song! He often "sings" but it's usually just sounds and verbal stims. He never says what he is not told to say and he spontaneously sang this song, over and over because, well, obviously he likes it! Which is a miracle and so cool that he had a preference for music, an artist, a song AND he's singing it! Katy Perry you should meet our beautiful son Jack who obviously loves you! :-) carlarobbins@sbcglobal.net
