From Heidi Murkoff, author of the world's bestselling pregnancy and parenting books, comes the must-have guide every expectant couple needs before they even conceive. Medical groups now recommend that all hopeful parents plan for baby-making at least three months before they begin trying. And who better to guide want-to-be mums and dads step-by-step through the preconception (and conception) process than Heidi Murkoff? It's all here. Everything couples need to know before sperm and egg meet. Packed with the same kind of reassuring, empathic and practical information and advice that readers have come to expect from 'What to Expect,' only sooner.
