I think you're all being a little harsh on OP. "Go play The Sims" could be used to shoot down pretty much any housing idea.
You can grow carrots and raise chocobos, so why not babies?
One neat thing about implementing Babies would be we'd finally get to find out what the babies of the races look like.
I'd probably never use it but yes, Square, please add a Babies feature. You can call it "A Realm Newborn" or something.
