Hi doctor. My niece was born in 2012. Ever since she was a child, she has slept at night or cried and struggled, the more her parents touched her, the more she cried and cried. Just let me scream and then I stop crying and go back to sleep. In the morning, I asked her and answered "don't know". I wonder if this situation has any effect and is it dangerous? How and where should my child be treated? Do you have any neurological problems? I have a bad temper, when I'm angry or yelled at, I cry and often tear my arms, legs and thighs. So, is the phenomenon of crying and angry children a sign of autism in young children? In addition, he is still normal like many other children, studying well, having fun with his friends, drawing and coloring beautifully. Please give me some advice
