I just came across a few videos that I thought do a fine job of explaining how kids, and in the case of the first video, especially biracial or multiracial children, can express themselves through puppets in liberating ways. Try to look past the low production values, as there’s some really good information here, both in terms of how children use puppets and how parents might encourage children to be creative through animating common objects.
