Parents play an important role in the development of children, and frequent parental quarrels may lead to depression in children. The main reason is that parents quarrel will make the child think that the family relationship is not harmonious, resulting in the child and parental intimacy reduced, so that the child is not good at seeking help when encountering frustration or difficulties, poor emotional expression, emotional irritability, etc., which in turn leads to the child’s negative emotions, increasing the chances of the child suffering from depression. In addition, the common factors that cause depression in children are as follows: 1. Genetic factors: depression has a certain genetic tendency, for example, if both parents are depressed, the child born from the combination of the two may also be depressed; 2. Social and family factors: mainly refers to the bad growing environment, as well as the sudden stimulation of major life events, such as the sudden death of relatives, parental divorce during early childhood, frequent quarrels between parents, etc. 3, other: parents are too demanding of their children, often criticize and suppress their children, causing excessive psychological pressure on the child, which may lead to the child’s poor ability to resist stress and easily produce self-loathing and pessimism due to small failures or mistakes, which may lead to depression. Therefore, parents should create a warm family environment for their children in their daily life together, and should choose the right time and occasion to solve the conflicts that arise in their lives. When the child is depressed, not confident, etc., should be given timely care. If the child has emotional abnormalities such as large emotional ups and downs, sudden drop in academic performance, reduced appetite, low self-esteem, yelling, etc., parents need to promptly take the child to the doctor to rule out the existence of depressive tendencies, if necessary, the need for dual treatment of psychological and drug.
