So my LO is 6 months old and he still naps in the Rock 'n Play. I know I need to transition him to the crib for naps, but he does so well in the RnP! I don't even usually have to rock him. He knows that's where he naps and he goes right to sleep. If I try laying him down in his crib, he will NOT go to sleep.

We don't CIO. How can I easily get him to switch napping spots? Or should I just keep letting him do what works?

FWIW, his nighttime sleep has been crap the last two weeks. Growth spurt, teething, wonder week, who knows?! But I'm kind of hesitant to change anything until he's sleeping better at night...
