Query: Provided Incorrect Information

This book is not helpful, in fact, some of the information is incorrect. I would not recommend this book. The information that I found unhelful or incorrect included:- the chapter on nutritian doesn't provide any dietary guidelines on what to actually eat!- recommends doing sit-ups during pregnancy. As your abdominal muscles separate to accommodate your growing belly sit-ups are not advised and can actually be harmful.- BUT: the most disappointing was the recommendation to take a folic acid or vitamin B12 supplement (which was repeted several times throughout the book so clearly not a typo). I would have expected a OB/GYN to know that folic acid is vitamin B9 and NOT B12. Vitamin B12 is Cobalamin NOT folic acid. I hope that no pregnant mothers have been confused by this very harmful misinformation.
