LO is nearly 10 weeks old. Right now, he naps during the day either on me/his daddy, or in his R&P. Overnight, he sleeps in the R&P. We're thinking of starting to transition him to his crib/the nursery for the overnights (and naps, too, when needed). I've read lots about this, but - any words of advice for making the transition as smooth as possible? Many thanks in advance from this FTM.
