I know that I read it.  I was able to get a load of information.  I know a lot of woman ask me what size the is at all different stages.  If I tell them and approximate in mm's, cm's or inches, they say "Well the book tells me the baby is the size of a mango.  I just nod.  I don't eat mangos, so I can't claim the size of the baby is that particular fruit size.  If you don't have it but are pregnant, I would highly recommend this book.
