This is my little sister
Leah's middle name. ♥
And no, I do not think it is too long to be used on it's own. And no, I wouldn't shorten it if I preferred it without a nickname.
And I know a girl named
Lexi who is indeed tortured with the nickname "Sexy
Lexi". And yes,
Alex is avoidable. Chill. Just introduce the kid as
Alexandria and that's what they'll call her. And besides, she might WANT to be an
Alex when she gets older, and when she decides, you'll have to live with it.
My favorite is
Alex or
Lexi.
And no, not too common.
