My answer to big behaviors with "its because of trauma” is Yes and No-
The yes is in reply to understanding that all behaviors often can be understood in light of trauma. What research has found about children who have experienced early relational trauma is that it results in complex developmental trauma. Sensory systems, cognitive ability, emotional regulation, and social ability (and more) are impacted by early traumatic relationships. I think TBRI is a useful model because it aims at putting children back onto a typical developmental trajectory. When we look at it as a brain that is “delayed”in areas, then it seems for me much easier to address the behavior. I aim to look at the developmental need behind the behavior rather than just dealing with the presenting behavior.
