When using wp_enqueue_scripts I should set a higher priority number.
But need to remove from parent themes css enqueue first, maybe something like this will work.
/**
* Proper way to enqueue scripts and styles
*/
function it_company_child_theme_scripts() {
wp_dequeue_style('bootstrap'); // from parent theme
wp_deregister_style('bootstrap');
wp_enqueue_style('bootstrap', get_template_directory_uri().'/css/bootstrap.css', 10);
}
add_action( 'wp_enqueue_scripts', 'it_company_child_theme_scripts' );
