Prince LOUIS ARTHUR CHARLES. Louie sounds like a Damon Runyon character. Artie/Chuck isn't much better. What will he be called?

Prince George hasn't yet been called "Georgie". Princess Charlotte hasn't as yet been referred to as Char. (That's too near Cher). With the new young 'un there is a chance that he'd be  Lou/Louie/Art/Artie/Charlie/Chuck/Chuckie.  SIGH. A nicknameless choice might have been better. Kids can be cruel.
