Adding text above posts on a blog page is actually very easy to do in Genesis regardless of what child theme you use. In fact, I do this for every site I create simply as a convenience for my clients. They don’t know they CAN’T without this but you never know if they will try.
1. Coy the page_blog.php file from the Genesis Theme folder into your child theme folder.
2. Open the copied page_blog.php file in your favorite editor.
3. Add this line above the genesis();
add_action(‘genesis_loop’, ‘genesis_standard_loop’, 5);
4. Save it and re-upload it.
