From a child victim's perspective, it's very important. Children will automatically appeal to the adult world around them and make sure that everybody is okay except themselves. That's an emotional response; that's automatic in development. They will take care of the parent; they'll even take care of the parent who may have abused them. It's important to understand what's happening with children developmentally, to begin with.
Second, there's a couple of initiatives, and one is the child-friendly court where they don't see the perpetrator. The other is remote testimony. In the event that a statement that has been recorded is not taken into court, the child may be able to testify remotely to the court.
It's unconventional, but I think it's absolutely necessary for the emotional well-being of the victim at that age. They are in no position to compete with the adult issues or challenges that are going on around them.
