According to psychologists, many parents have the habit of entertain their children since they were young, so most children will react if their parents do not meet the requirements set by them. Therefore, children will have symptoms such as crying, anger, loss of appetite...
The advice for parents in this case is to be tough and determined to refuse so that children realize that being angry will be ineffective. From there, children will be aware of their limits and the consequences if they intentionally break the rule.
In addition, parents spend time regularly chatting with their children, analyzing why parents do not meet their children's requirements. This will help children learn to be patient as well as the ability to analyze situations.
Depending on each case, point out strengths and weaknesses so that children try to improve themselves every day. At the same time, don't forget to give compliments, encouragement or give small gifts as words of encouragement when seeing the changes from children.
