Display the child pages and grandchild pages on the parent page in separate divs

So I’m trying to create a loop that puts all of the child and grandchild pages on the one parent page. My problem is that I also need to differentiate which is a child of the main page and which is a grandchild, so i can apply differently styled titles to them. here is the code I have now, but it’s not doing it for me

<?php the_content(); ?>
			<?php
				$ancestors = count(get_post_ancestors($post->ID));
				$pages = get_pages('child_of='.$post->ID.'&sort_column=post_date&sort_order=desc');
				$count = 0;
				foreach($pages as $page)
				{
					$content = $page->post_content;
					if(!$content)
						continue;
					$count++;
					$content = apply_filters('the_content', $content);
					$children = is_tree($page);
					$parents = count(get_children());
					 {

					if($children > 1) {
				?>
					<h2><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h2>
					<p><?php echo $parents ?></p>
					<p><?php echo $children ?></p>

					<?php echo $content ?>

					<?php } else { ?>
					<h3><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h3>
					<p><?php echo $parents ?></p>
					<p><?php echo $children ?></p>
					<?php echo $content ?>

				<?php } } }?>
