As for Joash's sleep (are you sick of hearing about this already?), his nights are still rather unpredictable, but he seems to be more consistently only waking up once during the night, which is still pretty good. Though now when he wakes, he doesn't really seem hungry, so I think I am going to have to try some other things to see what he needs to calm back down so he can sleep.
He finally seems to be falling into a more predictable nap schedule as well. He typically takes two 1-1/2 to 2 hour naps and then a 1/2 hour cat nap in the late after noon. It nice to know what to expect now when he goes down for a nap, since I am a person who likes routine.
