List Child Pages Only

Hello,
I’ve been working with the template tags, specifically the wp_list_pages() .

I was glad to find the argument of depth, to show only parent pages.

But, I have found the need to list just the Child Pages of a Specific Parent Page on a page. I was hoping there was another argument that I could pass in the wp_list_pages() tag to specify what parent page to use.

I would imagine it would look something like this:
wp_list_pages(‘sort_column=menu_order&title_li=&parent_id=5’);

It would be really nice to have this ability.

Any info would be greatly appreciated!
James
