Slightly odd one, but hoping you've might be able to help....
Bump has been known as Bunny since an early scan where she looked just like a (very cute) rabbit. Now we aren't going to call her Bunny.... but quite like the idea of a middle name that relates to rabbits/bunnies, but in a way that no one else need know. So not Flopsy or Cottontail...
Any ideas???
