Children often learn how to regulate their emotions and cope with stress by observing their parents. If parents model healthy emotional expression and effective coping strategies, children are more likely to develop those skills. On the other hand, if parents consistently exhibit emotional instability, hostility, or ineffective coping mechanisms, children may struggle to manage their own emotions and mental well-being. The quality of the parent-child relationship plays a very important role in a child's sense of security and attachment.
