hi friends, actualy my son is 4 years old, but since few days his behaviour has changed alot. He gets very angry on small things and starts crying on small things like sometimes he say to switch off fan and if we say no he gets very angry and even if we try to make him understand he starts shouting and throwing things.
we also gets irritated because of this behaviour.
