A bit of a first world problem, but...DD had a productive lunch time nap. When I checked on her she was laying down in bed. What I didn't know was that she had the belt to her good dress in her bed and chewed it so that it has bite marks all the length of it. It's polyurethane - is there anything I can do to try and make it smoother again. Would an iron help or would it just melt or burn it? It's not like I can just go out and buy another belt as this one came with the dress and she's only worn it once and it was an expensive one. So upset with her as this is just a long string of things that she is constantly doing...and her second belt - the last one she did this to had to be thrown out.
