Attributing a version number to a child theme’s main stylesheet

In header.php, I like to attribute a version number to the stylesheet so that the browser gets forced to refresh it. But when working with a child theme, its stylesheet is not explicitely called, rather WordPress automatically seeks it. So how or where to attribute a version number to the child theme’s stylesheet?

You can update the version in the child themes style sheet itself…

/*
 Theme Name:   Twenty Fourteen Child
 Theme URI:    http://example.com/twenty-fourteen-child/
 Description:  Twenty Fourteen Child Theme
 Author:       John Doe
 Author URI:   http://example.com
 Template:     twentyfourteen
 Version:      1.1.2 <---- Update here
