I think when choosing a unisex name that adding an “ie” can make it so much more feminine feeling! People could mispronounce, but people also mispronounce very basic names. As long as you like how it’s spelt as the parent who will write it and type it all the time, that’s all that matters!
I’m considering doing the same thing with [name_u]Baby[/name_u] #2 ‘s name. We like [name_u]Emery[/name_u], but may do [name_f]Emerie[/name_f] instead!
