Although children and teens might have severe responses to trauma, their symptoms may differ from those of adults. Symptoms in very young toddlers can include: Bedwetting after being toilet-trained Being unable to speak or forgetting how to speak Acting out the frightening experience during playtime Being too attached to a parent or another adult. Symptoms in older adolescents and teens are more similar to those experienced in adults. They might also start acting out in ways that are disruptive, rude, or harmful. Teenagers and older children may feel shame for failing to avert injuries or fatalities. They may also harbor vengeful thoughts.
