Listing parent and child on pages

I can’t seem to figure out how to do this. I’ve been searching for a couple hours and nothing seems to do what I want, or it lists everything regardless.

Sample

Resources is the main page, and underneath it, I want to list ONLY tutorials, and under the tutorial page, I want it to ONLY list wordpress, and under wordpress ONLY list the two tutorials.

Is there a way to do this? I want to be able to control how it appears without CSS, as it will never change. I’ve looked at various plugins and the wp_list_page and get_page functions, but it relies on wordpress to list everything associated with the page/post, and I want to be able to define the post/page ID if possible.

This will also be inserted directly into the page/post, and not into a template.
