I love
Anastasia pronounced the Slavic way (ah-nah-stah-SEE-yah), but hate the English pronunciation.
Anja is my fave nickname for it, but I'd probably just use the whole name.
I was considering it as a honoring for
Ana, but Croatian version is
Anastazija which I'm not a fan of, so gave it up.
Anastasia and
Isadora would be a wonderful sibset:-)
