This book has been around for 10 years, though maybe not in the U.S. The author openly summarises (well, re-writes) Jean Liedhoff's The Continuum Concept, just putting it in a contemporary British context. Most useful sections are on touching (eg. on why swaddling is always a poor substitute for a mother's skin), breast-feeding "failures" (women having lost so much confidence in their ability to feed their baby, a peculiarly western condition) and practical advice on how to avoid cracked nipples, engorgemnt etc - i.e. constant feeding, most importantly, night feeding. All chapters point to one given, that you must have your baby in bed with you at night. She even changes her doctor's mind on the subject, so beware, she'll probably change yours if you are a sceptic or have never tried it!
If you are afraid that "wearing" your baby will give you a bad back and will make you a martyr, read this book. The author states that her baby felt lighter at 8 months than at 8 days!!
The best sections are at the end, Practically Speaking (common questions answered) and Yes, but... (common accusaitons of co-sleeping rebutted).
Really good present for any new parent who is not getting a decent night's sleep.
