Instruct: Classify Amazon reviews into positive or negative sentiment
Query: A mediocre attempt for justification of a very one-sided approach

As a first-time father decided to get this book since it did look promising at first. Unfortunately should have checked out the one-star reviews. This is a terribly written book, based on questionable statistics. The "scientific evidence" that the author claims support her beliefs is questionable at best. It manipulates the facts and misleads readers into thinking that there is tons of evidence in support of her views. Just check the references -- statement after statement refers to the same book or study.In one word -- mediocrity.
