I see the parent but lost the child…HELP!

Driving me crazy…created a mobile site, main page has no menus…created a child page called “about” then put 4 more pages as child to the “about” page. For some crazy reason, I can only see the main page (parent) but can’t get access to the “about” and all other pages to edit! I have to show this tomorrow ?? HELP! Hope that makes sense!
