A workmate of mine who didn’t know what the sex of their child was gong to be explained to me that they picked a name they loved the sound of, and could use whether they had a boy or girl just by changing the spelling. They were looking at [name]Miller[/name] or [name]Mila[/name], and ended up with a [name]Mila[/name] 
I like [name]Pascal[/name]/[name]Pascale[/name]!
