could you describe how a child might act who does this
Thank you for being interested. Most "normal" people are not. It means a lot, even though what we have to say is painful.
There are all sorts of walls. One child might become terribly withdrawn and "shy". Another might become angry and violent. Still another might become overly sexual. Realize that each is a wall. By acting out, each child is telling not only what happened to them, and how they felt about it, but they are also showing you what it will take to "breach" their defenses.
A child who withdraws, is basically telling you that you can never reach them. They are always in reverse, and until they are ready, you can never, ever reach them.
A child who is angry and violent is the most upfront. Their defense is their anger and if you move in too close you will feel their wrath. These are also the children that are the most brittle. Realize that once you get past their anger, they have nothing left.
A child who "acts out" and is overly sexual is one who deals with the abuse by being so compliant they embrace the experience. They seek only to please. They are so fragile they cannot stand being hurt, so they will do anything to avoid being hurt. They retreat into the very essence of the experience.
Does any of this make sense? Sometimes I feel like I am posting in "short hand" and using metaphors and words that mean something to me, but may not to others.
