My all-time favorite is Nursing Mother's Companion, third revised edition, by Kathleen Huggins. I like it because, in a crisis, the pertinent information is easy to find. Engorged? There's an explanation of engorgement, then a step by step guide to relief. Nipples feel like they're going to fall off? Turn to that page.... I also like the "survival guides" for each stage of nursing. "How to survive the first week" is a real gem. I didn't like the title at first because I thought using the word survival was too negative, but I have found that by the time a mom comes to me with a concern, using the word 'survival' seems appropriate. I also like the appendices on determining babies' milk needs during the first six weeks and medications. I do wish the drug section gave references, though. I also like Kathleen Huggins' The Nursing Mother's Guide to Weaning. It addressed the mother's concern, then gives her suggestions for solving her challenge while continuing to breastfeed! It covers why a mother may want to supplement with formula, then gives her suggestions for solving her concern without supplementing with formula. There are also directions for estimating a mother's milk production and determining a baby's need for breastmilk based on the infant's weight. Moms have liked both books. Elizabeth
