I could be missing something here, but wouldn't specifying a depth as an
argument solve your problem? If you look at the
Codex<http://codex.wordpress.org/Template_Tags/wp_list_pages> for
wp_list_pages, there's an argument you can specify which tells WordPress how
far down to recurse. I *think* this will do what you're looking for.
eg:

$children =
wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0&depth=1');
