How to display data from child pages in wordpress?

Question

WordPress

Need in the /wp-admin/post.php page? post =5299&action=edit
Display information from child pages as blocks.

<div> IMG1 <br> title1 <br> text1 </div>
<div> IMG2 <br> title2 <br> text2 </div>

I can not figure out how to do this, apparently, you need to use get_posts.
