Show all posts on a twentythirteen multisite

I'm using the default twentythirteen on a wordpress 4.0 site. I have one site in the network right now. I may be adding one or two next year or so. Both blogs are using twentythirteen. Right now the "main" blog only loops out its own posts. I want it to include the child blog. Is there a good way to do this? Doesn't matter if i have to do some manual tinkering in the code when i add a blog to the network since i won't be doing that often.

Edit: i want the posts to appear in the main content area like the posts from the main blog. In the same default style as twentythirteen.

Edit 2: Clarification. The twentythirteen theme have "The Loop" in index.php.

?php while ( have_posts() ) : the_post(); ?
    ?php get_template_part( 'content', get_post_format() ); ?
?php endwhile; ?

If i could get that while loop too fetch the child blogs too i'd get exactly what i'm after. I know this will have more consequenses that needs to be addressed (the paging for example) but this is essentially what i'm after.

You can't just loop over all the recent posts in your network install. Each site in a network is made to feel as far as the API and most of user interface goes as a full stand alone wordpress site. It is both a strength and weakness of the system, but it means that doing anything which mixes content from various sites is not trivial.

The key is the function switch_to_blog and restore_current_blog that enable you to use the wordpress API in the context of different blogs

Since you want to have your posts displayed chronologically you first need to create a list of all the recent posts on all site, something like

$blogs_to_fetch = array( the blog ids of the blogs);
$posts = array();

// first we collect data

foreach ($blogs_to_fetch as $blogid) {
  switch_to_blog($blogid);
  $ps = get_posts(parameters to get N latest posts);
  foreach $ps as $p) {
    $posts[] = array('blogid' => $blogid, 'post' => $post);
  }
  restore_current_blog(); // not realy needed, but nicer to the eye
}

$posts = sort_posts($posts); // your own function that sorts the posts by time or by any other creiteria

// now we display

foreach ($posts as $p) {
  switch_to_blog($p['blogid']);
  setup_postdata( $p );
  get_template_part( 'content', get_post_format() );
  restore_current_blog();
}

// cleanup

wp_reset_postdata();

If you are looking for "easy", then the easiest way is probably to use the RSS widget for that. Get two widgets, one for each blog and you are done. Once you have a third blog just add another widget.
