It took a while, but it's coming together. He naps here during the daytime. He enjoys it and even hangs out in his little co-sleeper for a while alone upon waking. A few nights back he awoke after a dusktime nap and looked curiously all around at the dim, colorless, mysterious room, trying to reconcile it to the bright one he usually awoke in. The thoughts that run through the minds of babies must be interesting things. I can see him figuring things out in front of my eyes.
