Unfortunately, there is this book only in English! But do not worry, I think it is clearly legible even for less English Practiced. A very good book with many ideas for parents who are their child and themselves do not want to traumatize with "Let cry", but nevertheless already very hard from the night Supervise your child. I have in this book a lot about baby sleep in general, and what realistic expectations concerning the sleep of an infant. And moreover, that I do not have to wait idly until completely sleep readiness of my child matures naturally. This book passes on to meet in very strenuous phases his child with respect and love. And if anyone is interested, no, my son is still not sleeping through every single night. BUT! When he wakes up, he's asleep now much faster again, and he has already slept some nights - and for me are 4 hours or even 5 sleeping hours without interruption by 1 1/2 sleepless years a real dream.
