Who's in Charge???

He's testing you to see how far he can go without a scolding. I would say, ignore it when he does it because he's probably trying to get your attention at these times, even if it's to reprimand him. Maybe it would be a good idea to send him to a kindergarten if he doesn't already go, or some sort of pre-school activity, where he will have to learn to get along with other kids? Or maybe he will be starting school soon, where he will soon find out that this sort of behaviour doesn't carry with the other kids. When he goes into a tantrum, or shouting fit, close the door on him and walk away for a while. He'll soon realise that he's playing to himself and nobody else is going to come running. Good luck with this. A lot of children go through these sort of stages, so I wouldn't let it worry you too much unless he starts wrecking your home. lol. Brightest Blessings.

Your child needs his rump warmed up a bit with a good swift whack. His behavior is unacceptable and "explaining" is not going to work. Its unacceptable and he needs to learn that he can't do it. How? Tell him if he does this and this will be the consequences. What consequences? Spanking, sent to bed for 4 minutes (set a timer), take away his favorite toy. Obviously reasoning with him isn't working so its time to put your foot down and actually parent him. Its not abuse to spank your child. It is with love that you discipline him. Take a strong approach and stance and he will realize you are immovable in your decisions. If he isn't going to quit from a spanking them smack his mouth gently. If he yells in your face then deal with that FIRMLY! If he stomps or slams doors or throws toys out of anger then deal with that FIRMLY!. Don't let him get away with ANYTHING. And Time outs in a corner are unlikely to help.
