Can I use Mundi as a nickname?

Hello all,

Really loving [name]Rosamund[/name] for no.3. Struggling a little with a nickname for it (both her sisters have them so don’t want her feeling left out!). Best we’d come up with up until now was [name]Rosa[/name]. DH suggested Mundi which I actually quite like. Thoughts? Any other ideas?

Thanks!

I like it-- very sweet, and literary simultaneously. It reminds me of Australian nicknames like Bindi.

Sorry, it just reminds me of the fish, Barramundi…
