MIDDLE NAME - HELP ??!

Samantha • 20 - Expecting baby #1👶🏾💛
Our baby girl is due August 25th, we've had her first name for a while now, but could not think of a middle name that flowed well. So, we decided to not give her a middle name. However, just recently I've been thinking that I really want her to have a middle name. We like unique names, nothing too "simple" but it also can't be too unique as it would he too much with her first name. Any suggestions? 
Thank you ladies 💛  
Her first name is Avaeah 
Her surname is Frater 
So ... Avaeah Frater 👶🏽
