The Breastfeeding Book by William & Martha Sears
The book is easy to read and thoroughly indexed. Dr. and Martha Sears cover everything from the basics of breastfeeding, such as how to get the baby to latch on properly, father's role, working and breastfeeding, toddler nursing, and weaning. The authors' logical step-by-step approach is honest and realistic, and makes this a very accessible reference.
