Sleeping through the night

Last night (1/4/17) Ethan ate around 10:30 and was asleep by 11:30 so I was able to get in bed around midnight.  He woke up around 5am and Scott gave him his pacifier and then he didn't wake up again until 9am!  We were very impressed and I got a good nights sleep.  We will have to see if we can keep this up.  I would settle for a consistent 8 hours at night even.
