Good Night Moon...goodnight...what?

The other evening, I was getting K ready for bed. He was up on his changing pad and I was just putting the last diaper strap in place when I said, "Bye, bye penis." K has started calling his business by the anatomical name. We have no idea where he got this but we follow his lead. K replied, "Night, night penis." Then he turned to look at me and put his forefinger to his lips and said, "Shhhh! Sleeping." and point to his business. I cracked up!! My thoughts are that it should stay asleep for a VERY long time!!
