Okay, I gave in and left he monitor on.... BUT I had it turned waaay low and facing away from us. So, I didn't hear him at all. I don't know if that means he actually slept through the night or if he did wake and I didn't hear him.
If the last is the case, then HE LIVED!! and fell back asleep on his own.
For sure doing this again tonight.....
until tomorrow :)
