After a period of 58 months, researchers examined children's ability to correctly identify their emotions and they discovered that those who were exposed to more parental aggression were less capable of identifying their own emotions. In fact, the more prolonged their exposure to arguments, the more difficult it was for them to control their own emotions of abandonment, sadness, and fear. This translates into a greater risk of suffering from depression and anxiety later in life.
Arguments among couples may be perfectly normal, and although many try to control themselves and discuss things in private, away from children, others can't control the impulse and end up losing their cool. However, it's important to put yourself in your child's shoes and with their level of understanding. For adults, it may just be a colorful exchange of opinions, but for children, it could seem like the end of the world.
