This is another pregnancy organizer, similar to Pregnancy To-Do’s. This one has a bit more content, with information for each section. It allows you to keep track of your prenatal appointments, interviews, shopping list, packing list, and more. I found the lists in this book to be more extensive and in depth than the lists in Pregnancy To-Do’s. This could be a good thing, but in general I found that I prefered Pregnancy To-Do’s because it was simpler and easier. I liked the way 40 weeks + has a calendar in the front that you fill in dates with, and I also like the way they divide the book into categories with tabs. This one also had a weight gain log that I missed in Pregnancy To-Do’s. I ended up using both of these in conjunction. However, I think I relied on the Pregnancy To-Do’s as my work horse. And If i had to pick only one to have, it would have to be Pregnancy T0-Do’s. This was is also more expensive by $9, and that’s important.
