Making Child Pages managed by the WordPress as CMS

I have searched the codex and forums,but am not finding the answers I’m looking for.

I switched to WP so that I could use it as a CMS on specific pages of my site. I have a static front page and I have made all of my first level pages. Today, I spawned all of my child pages for one of my first level pages and these child pages are what I need to be using the blog type system on. When I created my static front page, I followed the codex and created a “blog” page, but now I cannot figure out how to make ALL of my child pages in the blog style so that I can update each page multiple times per day using the post system.

How do I do this? I can’t find the specific information regarding this problem. Thanks!
