I did this exact thing with CRC .She was going to be Cadence for the longest time until CRC just clicked and we fell for it.
Calli Grace is such a beautiful name, but it didn't click for some reason. I think partly because I knew a girl from our hometown that was named that.
I first believed she had to have a "C" name to continue along with the girl's names, but I think a "C" middle name does the trick just fine. One day she may be happy to be a little different. Either way, I am in love with the name!!
I cannot wait to meet you, Miss JClaire
