Hi there.
If you create the menu in the admin (Appearance > Menus) and then assign it to your theme you can arrange child pages under their parents by just dragging them to the right under the parent page.
For more help you can refer to the WordPress Menu User Guide

Fantastic! I can assign this custom built menu to appear at the top of the page instead of the auto generated navigation? Thanks so much. I’ll read the user guide and I’m sure it will walk me through it. THANKS again!
Yup, you can use this custom menu instead of the one automatically generated. Glad to help!
