Irresponsible advice that - by the author's own admission - contradicts many evidence based guidelines around sleep safety. Assumes babies should fit around a 21st Century, Western society lifestyle/ schedule and urges Mothers to ignore the evolutionary urge to keep babies close. Implicitly anti-breast feeding. As a mum, I found the approaches suggested in this book overwhelmingly unkind to both baby and mother and furthermore, to be at odds with safe sleep advice.
