What to Expect: What to Expect Before You're Expecting is the essential manual every expectant couple needs before they even conceive, written by Heidi Murkoff, author of the best-selling pregnancy and parenting books in the world. Medical organisations now advise that all prospective parents make plans for having children at least three months before they start trying. And Heidi Murkoff is the ideal person to walk would-be parents through the preconception (and conception) process step-by-step. Everything is present. Before sperm and egg meet, everything that couples need to know. packed with the same type of comforting, sympathetic, and useful knowledge and guidance that What to Expect readers have come to expect, only earlier.
