Here I am & I'll stick around just as long as I can before I have to head off to bed; 5:15am comes early here too, but I am a morning person, so that helps. Sounds to me like things are progressing and I haven't read anything to be alarmed about as far as time pushing goes. I agree that it sounds like the early light pushes bringing the puppy down the birth canal.
Hang in there little Honey, it won't be long now!
