How about a spit bath for a while? Can you take a bath and have something fun like a cup of tea and a cookie in it and bubbles? Maybe she'd climb in with you? And then you can let her take her own the next day with bubbles and a cup of tea?
Do you have a bathtub she doesn't use...maybe let her in that tub?
Maybe get a book at Barnes and Noble about taking baths....?
I don't know!!! Good luck!
