I adore
Charlie as a fn for a boy. It is probably in my top 3 at the moment but I'm not sure I can abide by putting it on a birth certificate. At the same time, I really dislike
Charles and I don't know how I would go putting that on a birth certificate either. I think it definitely can work on its own and I know men named
Charlie and it doesn't seem juvenile on them (like
Ricky or Petey or
Johnny does). At the same time, I wouldn't want my kid coming back to me when he is grown and asking why I didn't just give him a formal fn.
I love
Charlie so much that I have kind of resigned myself to using
Charles as a fn but I'd always call him
Charlie and introduce him as
Charlie. If he decided to go by
Charles as an adult, I wouldn't like it particularly but
Charles is a perfectly fine name that would stand him in good stead, just not my pick.
