With earlier, you mean WWI, I suppose (those two wars have been the only, where Germany was involved ... and the 1870/71 war.)
I'm a bit engaged in treatment of POW's ... in France. A friend recently wrote his PhD about it and I'm transferring my archive and collection to amuseum and archive there.
I don't think that in any war Germany (or any other involved nation) took children as POW - but I'm sure, you know better here again.
