All my kids do this every now and then. I think it is hilarious. What starts out sometimes as a well heard, healthy protest about taking a nap by themselves, eventually turns into a long, monotonous...something. Sunny is saying, "I'm not giving up...even though I'm exhausted...maybe just a little more noise and she will pick me up..."
Of course she saw the camera at the end. This is where the hilarity ensues. Because instinctively, I dropped to the ground in .2 seconds when she looked up at the camera. Instinctively? Really? Did I really need to hit the deck like I was on sniper patrol or something? I suppose I REALLY value nap time. At least things are continually interesting around here.
