I've also been paging through Olbermann's book, which is amusing, because it's just a collection of all the Worst Person segments, many of which I've already seen. But funny, nonetheless.
I now have the stack of sleep books. For that much money, it should be thicker. Ah, well. The two expensive sleep volumes (Steger/Brunt and Carskadon) are specialist collections of papers with (probably) some course use, which I think makes them more of a text and less of a monograph. But they aren't textbooks in any typical sense. OTOH, not as much appeal as that Breastfeeding: Biocultural Perspectives thing. The bindings on these things are pretty awesomely horrid, too.
You would not _believe_ how naptime is handled in Japanese day-care centres. Really exactly the way the world should work, if co-sleeping were normal, and we nurtured small children the way we should.
