Do you think parents should scold their children?

Part of raising children is instilling consequences for bad behavior. Whether you want to call this scolding or disciplining really doesn't matter, they amount of the same thing. To ignore that aspect of parenting all together is to refuse to do the job you've previously agreed to do, by having children in the first place. Kids push. That's what they do. You can talk until you're blue in the face, but every single kid pushes their limits to see what they can and can't get away with. And that's when the parent steps in, and through scolding (disciplining), we let them know what is and isn't acceptable behavior. That's scolding. So yes, it's not only beneficial, it's mandattory to producing children who learn from their lessons and strive to do better.
