Does the child hep-b vaccination hurt?

No. it will only hurt if you think about it. honestly , all it is, is a pinch. I got mine yesterday. I was over exaderating. it is nothing compared to the flu shot or h1n1. you will be fine. just don't think about it. if you think about it too much, then yes it will hurt . but that's mentally. so just relax. when it's done, you'll be like "that was nothing". good luck!
