Query: As someone said - too many complication discussed

This book was a waste. First of all, they delay important information till the end of the book (weeks after 30 talk about nutrition). Then (and this is bad) they would say that your baby's eyes are developing this week and here are things that could go wrong.How bad is that?!?!?!?This book is useless! Buy Mayo clinic instead - there if you want to look up complications you can search them at the end of the book, plus it contains much more information - precise to point and usefull.
