Wild child?

Right now, I'm sitting in my room and letting my nephew jump off my bed into a pile of pillows. He's laughing like a maniac and I'm just sitting her singing to him....what I mean by this is that I'm talking to him, but singing every word I say. *sings* "You are going crazy Brennen." He is yelling to me, "You are a wild child." Is this so? *ponders*
