I think it's really goofy on a boy, but I don't mind it with the nn
Sid. Only spelled
Sidney on a boy, though. I don't like it on a boy, but wouldn't mind meeting one, it's not horrible or anything.
I like
Sidney on a girl, without the nn
Sid. It just looks better spelled like this.
I don't really care for the
Sydney spelling. Definitely not on a boy. I don't mind it on a girl but wouldn't use it. The city is really beautiful, though.
It's very 90s dated, but getting less and less common and will probably be out of the top 100 in 5 years.
