I don't like Chloe-it's something about the way it sounds in English. Ugh. Also the Kardashian sister, although she uses a K.
Olivia is pretty, but I like
Sophia best. It's a beautiful and classic name. I know it's trendy and that turns a lot of people off (I want my child to be unique!) but I think that every child is unique despite the commonness of their name, and that will shine through.
