Query: A terrible idea!

If you are looking for a book on selfisness, this is it! As new parents, my wife and I were looking for something like this to get our son to sleep through the night. We made the double mistake of; a, buying this book and b, trying out the ideas in it. After a few nights of staying up, listening to our frightened child cry for his parents (and all of us getting less sleep than before I might add) we tossed out the book and went back to our old sleep patterns. So what if your child doesn't sleep through the night? Do you? Each and every night? Not likely. Everyone is different and what most new parents don't need is to be shamed into thinking this is the best system for them (see pages 77-78) he says 'shame' so many times I lost count! Save your money. Listen to your child and to your heart instead, belive me your can't go wrong that way!
