To this question I usually just say "we're still thinking about it." Honestly, I think we've already decided but I've heard horror stories from women on my BMB about all the unwanted opinions people feel free to express the moment you share the name so I'm a little gun-shy.
Along these lines, yesterday I was having a discussion with a coworker about naming your kids.
First she begged me not to pick any trendy/different names (ok well, not
sure how it affects you but we weren't planning to anyway) and when I
said we were likely going to stick with some family names and, if it's a boy, name him
after Hubs' beloved Grandpa John she proceeded to tell me she "HAAAAAATES
the name John because it's soooo boring".
Okay, well fuck you very much
and I never asked your opinion anyway.
Maybe we WILL wait until the birth to share the name. Oy.
