Rubes we have a name chosen for a girl that we both 100% agree on so we are not sharing it with anyone, last time everyone said they didn't like E's name and I got upset with my mum, etc, etc, and so there will be no sharing of it with family that's for sure!!
We are not decided on a boy and haven't even really got a shortlist properly yet, so I might decide to share shortlist with people secretly at some point, but will not be telling grandparents this time!!!
Also I suspect you are overthinking it, that is my problem though, it is so difficult to know connotations of name/things you haven't thought of, etc, if you don't discuss it with more people than just your DH!
I don't think there is a problem with super-popular name either! DH doesn't like them though.....so it makes things difficult for us.
Obviously I think you should tell us the names!!!
