Is he swaddled? That works great for us.
How is your room set-up? For us, we have the crib and a RnP in our bedroom. From day 1, we put him to sleep in the RnP, but after MOTN feed/diaper change, we put him in the crib to sleep for he remainder of the night. Sometimes he gets fussy during MOTN wake, and we put him back in the RnP when he's fussy. But for the most part, he will sleep in the crib. Last night we actually put him in his crib from the start and he slept there all night (with 2 MOTN feeds).
