You guys, this has happened:
Nikolai figured out how to get out of his crib, so we had to transition to a toddler bed. The first few days were awful (in which Niko skipped naps and got much less sleep than usual at night) but he adjusted pretty quick--within a week he had stopped spending naptime playing and was sleeping normally again. Also, I've only found him asleep on the floor twice so I think we're looking at a success!
