You don't have to worry about the children because there aren't any. If you look at any area in any planet where there are skeletons you won't see any kid sized skeletons. They're all adults. Any surviving children after the great collapse were the last ones. The only kid mentioned in the Grimoire is Shin Malphur. Then he grew up and murdered Dredgen Yor. So don't worry about the kids, they no longer exist.
