“One day you will find that you have stopped regarding your baby as an unpredictable and therefore rather alarming novelty, and have begun instead to think of her as a person with tastes, preferences and characteristics of her own. When that happens you will know that she has moved on from being a “newborn” and has got herself settled into life.
The settled baby is a manageable proposition. Above all, you can tell when she is happy, however seldom that may be, and when she is miserable, even if that is almost always.”
—Penelope Leach, Your Baby and Child
