Query: way too preachy

While probably containing valid and scientifically correct information, I doubt that even 5% of pregnant women are able to follow the suggestions in this book. This is most apparant in the insanely strict diet guidelines and alarmist presentation of what can go wrong. Also I mistrust any pregnancy publication that does not adequately prepare you for the pain of childbirth.
