The Child Whisperer is one of my most-referenced parenting books. It has given me a better understanding of each of my children (who are so very different from each other). With this knowledge, I have been able to better support them in being who they are, and have learned how to best handle parenting situations depending on their individual natures.Homeopathic Medicine at Home is a great book for getting started in treating acute illnesses with homeopathy. This book helps beginners gain a solid foundation which can be built upon with books such as Common Ailments of Children and Their Homeopathic Management.
The Baby Book: Everything You Need to Know About Your Baby from Birth to Age Two
is a must-have resource for all new parents. It is like a user manual for babies. In the early days of parenting both of my children, I referenced this book daily! 
So That's What They're For!: The Definitive Breastfeeding Guide is a wonderful resource to have on-hand for any prospective mother. It clearly explains the many benefits of breastfeeding and the mechanics of breastfeeding. It is great for trouble-shooting any breastfeeding problems, and includes sections on going back to work, weaning, and toddler nursing.
How to Raise a Healthy Child in Spite of Your Doctor is an invaluable book that details childhood illnesses and health. It provides the information parents need to make informed decisions when their children are ill. Before I learned about homeopathy, this book was essential whenever my children were ill.
Vaccine Safety Manual for Concerned Families and Health Practitioners: Guide to Immunization Risks and Protection
is a large book detailing the numerous studies that have been done on all different childhood vaccines. It is a great reference book for parents trying to decide what vaccines (if any) to allow for their children.
Vaccines: Are They Really Safe and Effective
is a smaller version of the Vaccine Safety Manual. A must-read for anyone who doesn't have much time, but wants to get information about the risks of vaccinations.
The No-Cry Sleep Solution: Gentle Ways to Help Your Baby Sleep Through the Night is an excellent resource for parents who want a gentle way to help their children sleep better. There are many helpful solutions in this book.
The Total Money Makeover: A Proven Plan for Financial Fitness
is a must-have for parents who need to stretch their budget. This book is the reason I was able to become a stay-at-home mom (despite previously being the breadwinner for our family).
NurtureShock: New Thinking About Children
is a book showing the latest research on a wide variety of topics, including discussing race with children, excessive use of praise, and children's sleep.
Buddha Mom
is a beautifully written book that will help promote calm and peace in your life. I gleaned lots of little insights while reading this book (and I am not a Buddhist). 
Buddhism for Mothers: A Calm Approach to Caring for Yourself and Your Children
is another very good book for promoting calm and peace in your home. This one is an easy reference book.
The Happiest Baby on the Block: The New Way to Calm Crying and Help Your Newborn Baby Sleep Longer I wish I had this book with my firstborn, but am thankful I had it with my second! I shows many techniques for soothing fussy babies, and I combined them with babywearing to have a wonderfully happy baby.
The Happiest Toddler on the Block: How to Eliminate Tantrums and Raise a Patient, Respectful, and Cooperative One- to Four-Year-Old This is a great book for learning why your toddler behaves the way she does and how to support and discipline her.
Diaper Free: The Gentle Wisdom of Natural Infant Hygiene
is a wonderful primer for anyone interested in teaching their baby elimination communication (which is a fancy way of saying that you learn how to encourage your baby to be aware of her eliminations). Elimination communication works wonderfully as both of my children were completely out of diapers before the age of 2&1/2.
