I liked this book alot because it was really more about practical ways to quell a baby’s fussiness than it was about preaching a doctrine of any sort. It’s just simple techniques that most definitely help quiet down a screaming newborn/infant. If you’ve been on an airplane/metro/train etc. with a baby who wouldn’t shut up, you can imagine the early hell of the 6-week colic peak for most new parents. This book is invaluable advice for coping and getting through it… until teething sets in, then all hell breaks loose for good.
