Is it normal that 3 years old, children start to yell/scream?

Screaming is common toddler behaviour. He could be screaming to experiment with sound, to get your attention, frustrated at not being able to express himself fully, or limit seeking. One way to deal with it would be like how one could handle a child’s whining – by not reacting to it. You will have to be firm and consistent in how you react to his screaming. You can stay around while he screams and say calmly to him that you will only help him after he is done with his screaming. In the meantime, put on a calm face and wait patiently for him to tone down. It is difficult, especially if you are outside. However, this is one of the better ways to teach your son that screaming will not get him what he wants. Explain to him after the tantrum episode that he will need to speak in his normal voice in order to you to understand him and help him. Over time, his screaming behaviour should go away. My friend’s son started screaming and whining at around 2.5 years old. Her son is easily agitated and would scream whenever he cannot get his message across. In the early days, he would get even more frustrated as my friend ignored his attempts and he would scream even louder trying to get her attention. My friend had to go through almost a year of teaching and “conditioning” before he finally learned that those methods are ineffective in getting my friend to respond to him.
