Caleb finally learned to roll onto his tummy to sleep at night. He's been trying for weeks and weeks, but he finally got it night before last. It hasn't been the miracle I hoped for as far as sleep goes, but it has helped a lot. Now he settles down for naps for a bit longer, and at night he's sleeping for about 4-5 hours at a stretch, though often his sleep is interrupted by a stuffy nose or a diaper changing need. I'm just happy he can get comfortable, though. Now to learn how to roll OFF his tummy!
