Child not showing

The theme by default appears to only show one child of a parent page, it will not show “grandchildren”.

From around line 38 of the header.php file:

<?php wp_list_pages('title_li=&depth=2&'.$hidden_pages)?>

Note the parameter ‘depth=2’ … you can read more about wp_list_pages() here: http://codex.wordpress.org/wp_list_pages
