With all the preparations that expectant moms make, one that often gets overlooked in choosing nursery colors and the perfect stroller is a memento for and about baby itself. And perhaps one of the best projects you could get started on now—while you are still relatively rested and not distracted by a crying baby—is a baby book.

You could write letters to your baby about what you’re going through in the pregnancy, your eating and exercise habits, the little choices you make every day, all to keep your baby safe and healthy. You could write about your hopes and dreams for your baby and tuck these letters in a page in your baby book. Most baby books have pockets in them for tucking away baby mementos. This would be a good place to keep these letters safe. They would make wonderful mementos for your baby to read one day.
