Possibly because he was nice and cozy all curled up (rather tightly I imagine) in mommy's belly :)
Since I got all of Connor's 12 month clothes washed and hung up ready for him to wear, I figured I better pack up all of his 0-9 month clothes. I almost cried putting the lid on. It's like I was officially closing the door on that part of his life. He has changed so much in the past month and I can only imagine how much he is going to continue to change!
