Yes, a 9-year-old child can experience trauma and potentially develop post-traumatic stress disorder (PTSD) if they witness or experience a violent and life-threatening event like the one you described in your novel.
Children are especially vulnerable to traumatic events, and witnessing a violent attack on their parents, especially when it involves an attempted murder, can have long-lasting and profound effects on their emotional and psychological well-being. Trauma experienced at such a young age can significantly impact their development, behavior, and mental health.
Children who witness violence or experience a traumatic event may exhibit various emotional and behavioral responses, such as:
- Nightmares and sleep disturbances.
- Flashbacks or intrusive memories of the event.
- Anxiety and fearfulness.
- Irritability or aggression.
- Difficulty concentrating or learning.
- Avoidance of reminders of the event or anything associated with it.
- Emotional numbing or detachment.
- Regression to earlier developmental stages.
In some cases, these symptoms may persist for months or even years, affecting the child's ability to function well in various aspects of their life, such as school, relationships, and overall well-being.
It's important to remember that trauma is a complex and sensitive subject, especially when involving children. If you are writing about this topic in your novel, it's crucial to approach it with sensitivity and accuracy. Consider doing thorough research on trauma and its effects on children, and consult with mental health professionals or resources to better understand the topic and portray it responsibly in your writing.
