A penny for your thoughts...

I find myself often wondering what is going on in Elise's little head. She has so many different expressions, and when sleeping her expressions cycle through all the different emotions -- she's even giggled a cute little baby laugh a couple times while sleeping. Apparently the cycling through the different emotions during REM sleep is very important for neural development, and its really fascinating to watch. I wonder, though....what does she dream about? And, when she's awake and making her funny faces...what is she thinking?
