The Children's Hospital of Philadelphia and the National Child Traumatic Stress Network have a lot's of resources that may help you. I forgot about these folks in Trauma Informed Acute Care for Pediatrics...they have a great site, toolbox, providers perspective, how to spread Trauma Informed practice throughout a healthcare system, after the ABCs, the DEFs (protocol for Distress, Emotional Support, remember the Family). I think this site will be helpful to you.
