How to Make Changes to Default Blog Display

My default blog shows multiple blog excerpts on the blog landing page. Example: https://www.inthelittle.com/blog-st-louis-newborn-baby-child-photographer/

Is it possible, instead, to have a blog landing page that displays the full length of a blog post, one post right after the next, beginning with the most recent post.

Of course, it would be nice to limit the number of posts that would be displayed on one page (for pageload reasons), so the ability to go to the next page of posts would also be helpful.

Is there a setting for this somewhere that I’m overlooking or is it possible to make this work (fairly easily) if I edit the code?

Thanks for your help!
