Getting child Pages with query_posts()

I am in the same situation and would love to know if someone has found a workable solution for this.

Don’t know if you can get that directly with query posts but the post_parent row in wp_posts is how you tell the child of a given page.

Here’s one example:

Also search the forums for post_parent for some other threads or click on the post_parent tag I added above.
