Auto sub-page previews
An alternative approach to outputting the above page previews is to tick the box saying "Display sub-page previews". The only catch with this is that you must want all of the sub-pages to display. The above approach you have more control over which pages to include and can tweak the page titles if desired. However it is more fiddly.
For the below to play nicely you should have a featured image set for each page and an excerpt (but it will work ok without).
