Keep calm
When parents face their children's emotions out of control, don't yell and accuse them loudly. Instead, they should keep calm and let the children release their emotions as much as possible, and then they will calm down after the children release their inner emotions. Parents can reason with their children calmly, and children are more receptive.
Divert attention
If the child's emotions are out of control for a long time and can't calm down his emotions, parents can try to divert the child's attention, let the child stop obsessing about the past, and then reason with the child step by step, let the child realize his emotional problems and teach his children how to control his emotions. Only in this way can his children become more mature and better face the setbacks and difficulties in life.
