Owen's First Sentence

Owen hasn't been much of a talker until recently.  You can usually understand some of what he says but most of it is just babble still.  He rarely puts two words together unless it is bye-bye _____ or night-night _____.  Imagine my surprise this afternoon when I walked into his room to get him up from his nap and he exclaims, "Hi Mama...I poop!"  Me: You pooped?  Owen: "Yeah!"  Me: "You sure did!"  Owen: excitedly jumping up and down in his crib!!!!
