You could always use Rosie for a nickname - use her middle name as your basis Lottie comes to mind for me. Although it's spelt 'lett', I tend to pronounce Scarlett with a slight 'o' sound so 'lott', ITMS.
I was thinking about that last night. Using her middle name or Lottie or even calling her Star instead of Scar.
I'm sure once we see her a NN will be easier. Well i hope so anyways.
