Was it a fluke or am I really going to be an easy baby?

Emily has already slept through the night! She went to bed around 10:30 last night and woke up to eat at 4am, so 5.5 hours, which is technically sleeping through the night. She then woke up again at 7:00 just in time for daddy to feed her before leaving for woke. Of course I was waking up every hour like clock work just to make sure she was still breathing!
