Sleeping through the night! (technically)

Last night Nolan slept through the night (technically)! I say "technically" because "sleeping through the night", as defined by the baby bibles, is 5+ hours.
For quite a while, we've been able to get a 3.5 - 4 hour sleep, following by another 2 - 3 hour chunk. But last night, he slept for 5 hours 15 min!!!
I will take this win, but I am still really hoping for 8+ hours. This would make mama a very happy - and a bit more sane - woman :)
