I agree Rosalind and Rosamund are good names. I know a Rosamund, but she’s always called Roz, which completely spoils it. That’s the problem with names that are easy to shorten.
I’ve noticed that it’s usual to give babies abbreviated names now. Alfie, Harry, Freddie, Archie are all in the top ten or so most popular baby names for boys. I think Charlie’s there as well. Call a child by whatever nickname you like, but I think the official name should be a proper one.
It’s not new. I had an aunt who was christened Bessie in 1919. As soon as she could, she changed it to Elizabeth.
