Richard R. Ramos calls ages 2 to 5 the "trainer" phase, when kids become aware of their desires and assert control, often through tantrums. Parents must shift from reacting to actively training them, setting clear limits and teaching obedience so children understand they're not in total control.

Now when the kids get a little older and they— in this stage from 2 to 5, I call that the role of the trainer. Because those of us that are parents, we know what happens when kids turn 2. Now they have a clue, and now, you know, they know what they want, when they want it, how they want it, where they want it. And if they don't get it, they can start throwing tantrums, crying, you know, and all those kinds of things. So during this time frame, another very important time frame, that's when we start to discipline them, train them. No, don't do that. Don't talk that way. Don't go that way. Go that way, you're going to get hurt. And we're kind of chasing them around because we know that they don't understand everything. So we have to train them about how to act, how to be. They want to be on the throne. They want to be in control. But we have to teach them, no, you are not in control, I'm in control. And what are we doing during this training? We're training them for obedience.
