Can a 2 year old have PTSD?

Understanding PTSD in Young Children

Very young children might exhibit some of the PTSD symptoms found in adults. This could be attributed to the fact that 8 out of the 17 PTSD symptoms necessitate the ability to verbalize the traumatic experience. Children at this age may display signs such as fear of strangers or anxiety when separated from their parents. Additionally, they might experience difficulties with sleep or suffer from nightmares.
