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! I still reference it very often.
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. I seem to use this book almost every single time my kids are 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.

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 my daughter was completely out of diapers before her second birthday.
