Kayden is a completely made-up, meaningless and extremely childish collection of sounds. It's also very dated, because it was unheard of as a name before the late 1990s. Besides that, it's a stereotypically trendy name that people use as an extreme example of low-class "kre8ive nayming." It's the Shaniqua of trendy, made-up names. There's nothing else I can really say that hasn't already been said about the other maiden-rhyming names. Don't use this name.

I've never been a fan of the whole -aden trend for boys, and silly kreatyv spylyngz like this make me hate it even more. At least Caden looks a little bit more intelligent than Kayden. I just saw a self-published book with a character (not a child) named Kayden, and I had to roll my eyes. If you're going to try to predate naming trends, at least use a name that existed when your character would've been born!
