The only thing I can guess about this would be that the chrome plating is causing the reaction. You may want to consider going to a hardware or farm supply store (if they're in your area) and buying something without any plating on it. Hopefully this will work.


Also, if you do buy them from there, remember to wash them thoroughly before using them as they will be coated with a light weight oil. This could possibly irritation or an allergic reaction with her skin.


Wish I could be more helpful.
