Only Display Immediate Children

Hi there

I need to add a sidebar for navigation for only the immediate children of a page, not its grandchildren.

I found a piece of code which displays children and grandchildren:

<ul class="sidebar">
<?php wp_list_pages('child_of='.get_the_ID().'&title_li=<div class="sideTitle">'.__('Next Steps').'</div>');
?>

Any ideas on how to make it only display immediate children?

Cheers

Richard
