"I'm totally stuck," said a mother to me recently. "Every time I try to set a limit with my son, and I tell him how I feel about his behavior, he either ignores me or says in a snotty voice `I don't care!' If I try to follow through with a consequence, and tell him I'm going to take away his Nintendo, he also says `I don't care.' I just don't know how to discipline him. He doesn't care if I do, so it has no impact."
