Hi Karen,
You did right but did you load the translations AFTER the theme setup?:
// add the translations if needed
add_action( 'after_setup_theme', mytheme_child_theme_setup' );
/**
* Setup the child-theme's translation file
* @return [type] [description]
*/
function mytheme_child_theme_setup() {
load_child_theme_textdomain( 'tm-beans', get_stylesheet_directory() . '/lib/languages' );
}
