The situations are similar: At the supermarket checkout, your child desperately wants a chocolate bar and starts screaming at the top of his voice when you say "no." On the way to daycare, your child angrily refuses to put on his winter jacket, even though it's cold. Your child rages because he doesn't immediately succeed in putting on the colorful socks by himself. And in the evening there is an angry haymaker drama in the bathroom because your child doesn't want to brush his teeth today. There are big tears, a lot of fussing, and maybe your child even lashes out. Does all this sound familiar? Don't worry: this behavior is quite normal in the age of defiance. You can hardly prevent the violent outbursts of emotion, and as parents you have done nothing wrong.
