I am looking for recommendations on books pertaining to sleep and sleep training of babies. Our little one is not colicky or fussy (we are lucky!) and it seems like many of the books I've seen are geared towards that. I'm looking for some books that will help me understand how to transition LO to sleeping more at night and when/how to establish a nap schedule for a newborn. I understand all children develop differently and have different needs, but I'm just looking to arm myself with as much knowledge as I can without having to buy 25 books. What book(s) did you find most helpful and in what ways?
