child theme multiple css files

I have created a child theme. Right now functions.php file looks like that:

<?php add_action( ‘wp_enqueue_scripts’, ‘theme_enqueue_styles’ );
function theme_enqueue_styles() {
wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/style.css’ );

}
?>

There is more stylesheets that I want to include in the child theme:

bootstrap.min.css
default.css

I tried to add:

wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/bootstrap.min.css’ );
wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/default.css’ );

but all I got was errors and the page did not even dispay :/

How should the code look like?
