Show tab bar when viewing pages nested within other tabs

How do you view pages that are children of another tab (or the tab main page itself), from within another tab and keep the tab bar up?

For example:

If I have:

  • Home Page tab
  • sub page of Home Page called Child1
  • Library Page tab
  • sub page of Library Page called Child2

How do I view Child2 from the Child1 page while keeping the tab bar visible?
How do I view the Library Page from the Child1 page while keeping the tab bar visible?

It looks like routing was changed to remove that weird (one:one) syntax and I’m not sure how to view a page thats served from one tab’s outlet vs another to keep the tab bar up.
