Article in English: If your child acts differently than they used to before the event, it may mean that something is wrong. Look for an increase in anxiety-related behaviors. It's common for children to start having difficulty with everyday life after experiencing a trauma. They may resist things like bedtime, attending school, or spending time with friends. Their performance in school might slip and they may experience behavioral regression. Take note of anything that's become a problem after a traumatic event.

A traumatized child may become extremely upset if this person or object is not with them, because they feel unsafe.   Children who have experienced a trauma may develop separation anxiety from parents or caregivers and fear being apart from them.  Some children withdraw and "disconnect" from family or friends instead, preferring to be alone. Children who have been traumatized may have difficulty falling or staying asleep, or resist bedtime.

Reassurance from adults is unlikely to soothe their fears.  Some children may obsess over preventing the event in the future, such as constantly checking the smoke alarm after a house fire. This may turn into Obsessive-Compulsive Disorder. Children might replay the event repeatedly in their art or play, like drawing the event over and over again, or repeatedly crashing toy cars into things. Adults were not able to protect them in the past, so they might reason "who can?" and decide that nobody can keep them safe. They may not believe adults who try to assure them.   If a child has been traumatized, they may have difficulty trusting others as a defense...
