Except, newborns are normally nocturnal. They are most awake at night, supposedly they sleep during the day in the womb as mommie is moving around, and they wake up at night when things are quiet. So, a feeding that might take 20 minutes actually drags on for an hour or more of trying to get the kid to go back to sleep. In Nolan's case, he's happy to sleep in your arms, but not so happy to sleep in his crib... only at night. And I can't really sleep with him in my arms. Or rather, I probably could sleep, but it would be a really bad idea.
So, instead of 2.5 hours of sleep every 3 hours, its more like 1 hour of sleep every hour. Doesn't make for much sleep.
Haven't really found any solutions for the "only sleeps in my arms" part.
