Exclude from posts?

I have a video site and I use a plugin that displays a report button. I have edited it so that it only shows the report button on the pages that have no children (the videos) successfully.

$pagekids = get_pages("child_of=".$post->ID."&exclude=166,206,230,1127");
if ($pagekids) {}
else {
return $text;
}

My problem is, it is also showing up on my posts which I don’t want it to do. Help please!
