This book is thorough, complete, and provides valuable advice without being judgemental and without claiming to know your baby or every baby. The authors base their advice on years of experience of medical practice, evidence-based medicine and their experience as parents. This provides a great combination of sources of parenting advice. It contains help with breastfeeding, bottle-feeding, if you're a biological parent, adoptive parent, parent of twins, parent of fussy babies, and even if your baby has special needs, so I don't really know why some comments here say that the book isn't inclusive of non-biological parents. This is THE most inclusive book i've read so far.
