The Baby Book by Dr. William Sears

700 pages of attachment parenting. Encyclopedic even if you pick and choose.

Dr. Sears popularized attachment parenting and this 700-page tome covers everything from birth to age two with encyclopedic thoroughness. Co-sleeping, babywearing, extended breastfeeding — it is all here with detailed how-to guidance. Even if you do not adopt the full attachment parenting philosophy, the medical reference sections on infant illness and development are invaluable.
