As requested by John John's aunts, here is a recent video.  This is my first time to add one, as Luke is usually the video blogger.  John is going to be 4 months on Friday!  Get ready for some sleep training, little boy.  The last few nights he has been waking up every three hours to nurse (not unusual) and taking over an hour to put back to sleep (unusual).  Exhausting.  This is the motivation I need to research a good sleep training method.
