I have 2 yr old daughter. Whenever her request is not full filled she start crying and suddenly goes into some state that she keeps getting angry and crying. It's less cry and more anger. She keeps changing mood in that state. She becomes so angry that it's hard to handle her and she keep shouting in anger Is this something normal? Today we consult one doctor and he said child doesn't have any physical illness. She cried atleast for 30-40 min in anger. Kindly help
