I read it after learning that my wife and I were expecting identical twins. This book seems made only for future parents to panic, since it focuses only on the negative aspects: the dangers to the mother and fetus during pregnancy and childbirth, psychological problems during childhood and teen, couple conflicts caused by multiple births, inevitability of divorce among parents, impossibility to take care of two infants and babies at the same time, and so on. This book is scary it will fill your spirits for a long time. And what you read does not match the hard reality fortunately. The twins is difficult, but with love, organization, dialogue, lots of patience and perseverance (and support obviously) it is doing very well.
A dismaying lack of tact and psychology of the authors, or perhaps they simply lack of competence and they talk about a topic after all it does not mastered so well.
