When parenting children with past trauma it is imperative to recognize that healing comes with it's own set of difficulties. The unfortunate consequence of healing is having to address and feel the tremendous pain from yesterday that had been previously hidden by anger and defense mechanisms.
When a child experiences trauma, they experience the same kind of adrenaline rush that comes when a normal person is in a crisis that allows them to pick up cars, be crushed and feel no pain, or break bones and keep walking towards safety. Repetitive trauma turns the adrenaline switch on full time. As the child heals, and learns that they are safe, the adrenaline switch eventually turns off. When it goes away, all they are left with is their wounds. This is where the healing begins.
