M.S.
I'm not trying to dismiss you because sleep deprivation stinks! But you are going to MISS this stage. I loved baby babble and it's so wonderful that he isn't crying every time he wakes! He sounds like a happy little guy that loves to hear himself talk. If at all possible, try and get him in his own room (or walk in closet, even). Baby babble at night sounds even better muffled. :)
