Stuck in a rut...

Amanda • Married to the love of my life. We have two daughters, currently trying for baby #3.
I have been over my baby name book of 10,000 names literally A to Z several times, I've been over multiple websites and communities and we just cannot find a name for this sweet baby girl growing in my belly.. I know I'm only 16 weeks and still have 24 weeks to really decide but I feel like I just found out we were expecting and now we're 4 months along.. Next thing you know it's gonna be New Years than April and delivery time... I just want a name for this sweet girl. Our first daughter is Sophia Louise, we want another name that's sweet and elegant and not extremely popular. I like unique and just feel like im never gonna find it...
