I read this book after hearing a great deal of controversy about it. Some of it seemed fairly straight-forward, and some of it was horrifying. The baby is treated as a little robot that can be programmed for the parents' convenience. I was shocked – it goes against every maternal instinct I've ever had. It also puts the mom on a schedule that might not work at all for the particular baby, which can lead to an early sense of failure.
Here are some reviews on this book that you might want to peruse. Please read the lowest ratings, in addition to the highest. There are some compelling reasons not to take this route, given by parents who have tried it: http://www.amazon.com/Becoming-Baby-Wise-Reference-Worldw...
I recently met a friend of a friend whose baby, now over a year, has failed to bond with his mother. and the situation is terribly sad. She deeply regrets using the Babywise approach, believing it to be the basis of the problem. Yet her son seemed "content" to start sleeping through the night at about 4 weeks old.
Parents, when contemplating children, don't always realize that the kids' needs will ideally come first for the first few years. It's part of the package, and the grownups are the only ones who get to sign on that dotted line before conception. Of course it's hard, when experienced parents warn how very demanding and exhausting it will be, to understand the reality of that. Wouldn't it be great if there were a way to "test drive" all the demands, so we can decide if we're up to it?
I've known so many young parents over my 45 years as an adult, and a lucky few have babies that sleep well, but most don't. I've watched all sorts of approaches to sleep techniques / training over the years, and honestly, the babies I've known who were attended to more ungrudgingly in their first year or so, even when it made extraordinary demands on the parents, really have seemed to settle into a more secure and happy childhood. Perhaps it is only that those parents were the most willing to answer all the exhausting demands of parenting, but It seems to me that those children who know they will have their needs met they tend to be less needy, anxious, or even angry, than kids whose parents had expectations that they "should" sleep earlier, control their impulses sooner, or behave more conveniently.
