Too stinkin' cute is what it was! My DS, who is 2.5 yo, was sitting in the living room floor this morning singing "Itsy Bitsy Spider" to his own music. He'd stuck one end of a rubber band type thing between his toes and was holding the other end in one hand and was "plucking the string, as it were, to make the music for his serenade of "Itsy Bitsy Spider" to all of us. When we applauded his performance, he commented that he was making music!
It was so cute! Of course, five minutes later when he decided to make a different type of music in the form of shrieks and screams, we weren't as impressed. Oh well, it was precious while it lasted.
