Japanese speakers -- what is Winter Child in Kanji?

I think it is 子

Please tell me this isn’t for a tattoo.

I know what’ll be a good idea: I’m a Capricorn, so I’ll get “winter child” tattooed on me in Japanese (since I’m an “otaku”). But since I don’t actually read or speak Japanese, I’ll ask strangers on the Internet to tell me. Because the internet isn’t rife with the danger of people trying to have fun at the expense of others, and there’s no way I’ll end up with the Kanji version of “arseface” or worse.
