Hey Erin,

My best friend is called Rosie..just Rosie and not short for Rosmary or anything else. She doesn't seem to have a problem with people assuming it's short for something. I also know of a toddler called Frankie too, that's the name on the birth cert and not a nick name.

If you are always going to use the shortened name then I can't see the point in putting the long version on the birth cert if you don't want it.
