title: Select last child, and ensure it is not the only child?
body: <p>I need to wrap a div around content only if it is the last-child. The problem I have with this code is that it will execute if there is only one item. So i want to know how I should check to use the :last-child only when there are mor than one children. If there is only one child. I do not want the div added. Here is my code:</p>
  
  <pre><code>$('div[class^="columns-"]').each(function(){
     $(this).find('div[class^="column"]:last-child').each(function(i){
         $(this).wrapInner('&lt;div class="col-last" /&gt;');   
     });
  });
  </code></pre>
