My thinking on Children puppets is that they can be made the same size as regular puppets so that the hair, heads, animations, accrsories, hand helds, etc. can be re-used. I copied the Male01, changed it to Child01, changed names in the files needed, and set the scale to .005 in the "properties file. . Sure beats starting from scratch. It is cool that the scale in the properties file adjusts everything about the puppet.
I figure the universal head can be made to look like a child's head, and the body meshes can be tweaked for children in Milkshape or Misfit.
