I'm having my third girl and all my children have "diff" names. My oldest is Callie Brianna second is Ashlynn Renee and the new baby is kyla Jo. I always get compliments on the names and I love it.
My friend recently called hers corah-may which I think is nice n another was medi-rose
I have no ideas for you. I've always put that pressure on my childrens' father. My daughter is named after my mother who passed shortly after she was born (crazy enough.) Her name is Amelia. My request was something that I could shorten and something that made her feel empowered. We call her Mia! :) I would suggest looking at history for ideas just because it's worked for me.
