Watching my belly MOVE! I was laying in the bath this morning feeling kicks and out of no where I saw my stomache by my belly button jump I thought maybe I was imagining it so I got creative and put water in my belly button (like in jurassic park when they saw the water jump :P) and waited and then WHAM there is was again and the water all moved too.
That might be the coolest thing to date. I was having such a crappy morning too, and LO just cheered me right up!
