Pagination for Pages is a very simple plugin that creates navigation between pages (or any other custom post type) with the same parent.
This plugin gives you one new function, pagination_for_pages($getPagesQuery='sort_column=menu_order&sort_order=asc')
- getPagesQuery – Passed directly to get_pages, read the codex to find all available options. Defaults to menu_order ascending & pages.
