So I guess American Idol is out?

Henry and I were laying on the bed this evening, winding him down towards sleep. I had just nursed him and his head was in my lap. He was sucking contentedly on his pacifer, and I was stroking his hair and forehead. His eyes were fluttering and I started to sing to him quietly. He looked straight at me and started giggling with the pacifier still in his mouth. Do you think he was commenting on my singing ability?
