Apologies, this is half a thread about a thread. Or lots of threads.
I feel like I read loads on times on Baby Names comments that 'nicknames develop over time', or how you shouldn't start with a shortened version and work out to a longer name.
Obviously this applies when your child is still known as Moo because she made a noise like a cow when she was a baby... But not when you're thinking that you want to call your daughter Katie, and then work out to decide of they should be a Katherine, Kathryn etc.
Is it just me, or is it actually quite common in RL to decide at the start that you want a Benjamin nn Ben, William nn Billy, Elizabeth nn Libby etc?
(I should qualify that this isn't exactly bothering me. I'm slightly bored this afternoon...)
