Breastfeeding may be natural, but it is not always instinctive. The 20th Anniversary Edition of this classic guide to breastfeeding, beloved by a generation of women, has been completely revised and updated to provide even more practical, reassuring advice and support for today's expectant and nursing mothers. Easy-reference survival guides help identify and resolve problems at each stage. An appendix on drug safety is a unique feature among breastfeeding books.
