Yeah, we got really lucky with Kaylee, she was always a night sleeper ... well sort of lucky, since I'm not really diurnal, but am rather nocturnal ...
As for the books, yes. I feel that most of them are detrimental and written by quack new-age hippy psychologists. One of the books we were given literally told us to place crystals next to our daughter when she slept to keep her "biorhythms" in check.
