Is this OK for my function.php?

I wonder if someone might be good enough to just check this bit of code. It works OK so that might mean I’m on the right track. All I am trying to do, in my child theme is use a theme specific hook to add some HTML.

function bts_social_share() {
        if(!is_feed() && !is_home()) {
               include_once( 'social-share.php' );        }
        }
add_action ('reactor_post_footer', 'bts_social_share');

Thanks
