WordPress Child Pages

To get the child pages of a WordPress page, update options using query_posts or WP_Query:

$options = ( object ) array(
	'order' 		=> 'DESC',
	'orderby' 		=> 'menu_order',
	'post_parent' 	=> $pg[ 0 ]->ID,
	'post_status' 	=> 'publish',
	'post_type' 	=> 'page',
	'posts_per_page' => 100
);
WP_Query( $options );
