We slept! All three of us went to bed at the same time for the first time. Ewan slept from 9:30pm-6:30am! He was up every few hours to eat of course, but went right back to sleep. What a miracle! I don't know how he did it, but I hope he does it again. :)
.UPDATE: Sadly, this hasn't happened again since. We'll keep working on it.
