Despite Brazelton's medical degree and experience I found this book as mixed and confusing as most of the "baby whisperer" genre of baby books. His observations based on real research and larger bodies of evidence are sometimes helpful but his personal opinions (most of the book) are often infuriating and quite prejudiced (i.e. it's better to have more than one child because a sibling forces a child to share. Good God) I prefer Penelope Leach or Sears for good common sense insights and less moralizing.
