I wouldn’t worry about that too much. They’re hot names and hot names age fine. Twenty years ago it was probably impossible to imagine [name]Jennifer[/name] as anything but a teenager, but she’s invaded the corporate world now with the same gusto that she invaded the playground. And her assistant, [name]Brittany[/name], will be calling the shots in a few more years.
I might press for [name]Charles[/name] with a [name]Charlie[/name] nickname, but [name]Brady[/name] and [name]Aiden[/name] will have presence when they need to, because all the other Bradys and Aidens will mature at the same rate.
