Query: I would give this less than one star if I could

This method totally did not work for our baby. Trying it made me sob into my pillow every night as my baby screamed. We shoehorned him into the routines during the day with absolutely no benefit to be seen at all at night. The advice in this book is overly preachy on many points and completely vague on others. For example: "baby must be in his cot and asleep by 7pm" but there's no real mention of HOW to get the baby asleep by 7 when he's not tired, other than you shouldn't let him fall asleep with a pacifier in his mouth. OH - but you can get further advice on Gina's website! Hooray! Except that to view anything on the website costs a further 60 pound fee! Not so hooray. Save your money and don't buy this book.
