Apart from deciding which hat to wear to Ascot, whether or not to have a baby is probably the biggest decision a person can make. Whether you want a child to brighten up the East Wing, avoid a succession crisis, or simply to get more out of Mother's Day, pregnancy and parenting are often the best way to achieve this. But getting there can be far from plain sailing, even if you're a champion Yachtsman (or woman!). From conception to your little prince or princess's first birthday, this invaluable guide will lead you by the hand through the common questions and worries you will face, including: Does 'nesting' mean I have to live in a tree? Which are the best supplements to take? ES Magazine or Sunday Times Style? Is caviar suitable for weaning? And many, many more. With practical advice from one of England's most expert ladies, When One is Expecting is an invaluable guide for anyone who has ever thought about having, had, seen, or been a baby.
