than waking up in the morning with sunshine coming in through your window, a tiny boy snuggled in bed with you, and realizing that you got over 8 hours of uninterrupted sleep, and that you feel good.
Jonathan seems to have completely made the switch to full nights of sleep. He nurses off to dreamland, transfers into his crib, and then doesn't wake up until 5am or so to nurse. Which means that I don't have to really wake up until, oh, 6am or thereabouts.
Sometimes I think I'm crazy to want another newborn. :)
