How can you name someone you haven't met yet?

Teja

I tried to look through a names book and I couldn't find any names I liked (this book is full of popular names from 2012) My SO's response was 'how can you name someone you haven't met yet'. The struggle is so real!! I feel like we won't find a name until the baby is here and we'll just be calling him /her baby for a couple of weeks😏
