Bridge ponders asking whether the child is actually a child or just an adult who prefers to stay disguised as one. But that would be silly.

I would collect more information, because while any source will have a bias, a child's bias can be especially misleading. On the other hand, the child of a warlord may know things about the military that outside sources would not. So I'd find another source, and then compare the information I got from the two sources before making my decision.
