Child Site doesn't appear in the Network menu

Question

As you see in the snapshot, just the main site appear in My Sites menu, Although it appears correctly in the "Network Admin".

I used the subdomain installation when I configured the Wordpress MU. And this is the Wordpress MU part in wp-config.php

define('WP_ALLOW_MULTISITE', true);

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'www.mydomain.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

Answer 1

I found the solution , it's dead simple, I should add myself to the child site as a user, I guess this should be done by default.
