What's He Singing?

 Recognize the song?




I can't tell you how much it means to me to see this.  For over a year we wondered if our boy would ever be able to verbalize and talk.  To see him not only talking, but singing, and doing it all on his own cause he's in the mood, is absolutely astounding.  And sweet.  And joyous.  And heart-tugging.  I can even understand over half of the words!  I love this little guy.
