You can create extra custom pages for your child's yearbook. Here is an article on how to add additional custom pages:
You may want to delete some of the extra custom pages which were added.
1. Go to your child's custom pages and click on the trash can at the bottom right corner of the pages you want to delete.
2. Confirm that you want to delete the pages and select Delete.
Note: If you have added extra custom pages but have not paid for all of them, when a paid page spread is deleted an additional custom page spread will move into the paid slot.
