How do I give edit permission to certain people to all child pages at once?

[Jong Won Kim]

I have many child pages and want to give edit permission to certain people at once, instead of editing each child page.

Hi! View restrictions are inherited so a restriction applied to a parent page will cascade down to any child pages.  Edit restrictions, on the other hand, are not inherited so you'll need to restrict pages individually unfortunately. 

Hope this helps.
