My grandmother never cared that we used to play with the nativity characters, dolls, and plushies all together. Y4es, me and my sister even incorporated the nativity story into our games. It was one of the reasons me and my sister never minded the stories of the nativity and christian religion as stuff like that was never held so sacred it became something to be punished for to use them in other ways. I never felt offended by the nativity because I saw it, and I remember the story because I heard it over and over. I do have to say baby jesus was the most boring character there.
