KW: I really think — and I don't mean this to be — but I really do think it's sort of a little bit of both. Yes, a healthy, mellow, or angel-like temperament baby definitely has an easier time falling into a sleep and eating schedule and is going to sleep easier. Most babies need gentle guidance from us, their parents, to learn how to put themselves to sleep and back to sleep once they're old enough, which usually is around 16-18 weeks if they haven't already started to do that on their own, which some "angel babies" do. Usually though, even those angel babies' parents have inadvertently done some things differently, like occasionally put them down on the more awake side than the sleep side.
