I bought this book as a reference for my oldest daughter to see what her little brother looked like at different weeks throughout the pregnancy. As far as that goal, this book was suitable. I do wish it had more week-by-week pictures and descriptions, rather than skipping a few weeks here and there. I know some weeks there isn't much of a change, but it still would have been nice.
The lovely photo of the placenta did a great job at testing my husbands gag reflex.
All-in-all, it wasn't a waste of money, and it will stay on the bookshelf for future reference.
