We're expecting again! Announcing the COMPLETELY REVISED AND UPDATED FOURTH EDITION of this bestselling pregnancy book. This is a cover-to-cover, chapter-by-chapter, line-by-line revision and update. It's a new book for a new generation of expectant mums, featuring a fresh perspective and a friendlier-than-ever voice. Heidi Murkoff has rewritten every section of the book, answering dozens of new questions and including loads of new asked-for material, such as a detailed week-by-week foetal development section in each of the monthly chapters, an expanded chapter on pre-conception, and a brand new one on carrying multiples. The Fourth Edition incorporates the most recent developments in obstetrics and addresses the most current lifestyle trends (from tattooing and belly piercing to Botox and aromatherapy).There's more than ever on pregnancy matters practical (including an expanded section on workplace concerns), physical (with more symptoms, more solutions), emotional (advice on riding the mood roller coaster), nutritional (from low-carb to vegan, from junk food-dependent to caffeine-addicted), and sexual (what's hot and what's not in pregnant lovemaking), as well as much more support for that very important partner in parenting, the dad-to-be. Overflowing with tips, helpful hints and humour (a pregnant woman's best friend), this new edition is more accessible and easier to use than ever before. It's everything parents-to-be have come to expect from What to Expect...only better.
