Language trouble – but child theme uploads OK

Hi,
I’m blind – why does this not work?
I changed the languages files to Norwegian with PoEdit, saved them as nb_NO.mo /nb_NO.po – and put labguage files in a new folder:
hueman-child/languages/

Read about language settings in child themes on WP and…
Changed functions.php in hueman-child folder to this:

<?php
/**
 * Setup My Child Theme's textdomain.
 *
 * Declare textdomain for this child theme.
 * Translations can be filed in the /languages/ directory.
 */
function my_child_theme_setup() {
	load_child_theme_textdomain( 'hueman-child', get_stylesheet_directory() . '/languages' );
}
add_action( 'after_setup_theme', 'my_child_theme_setup' );
?>

— The child theme uploads fine, but it’s still in english. What am I not getting? I’m going nuts!
