I'm not saying that too much of a good thing isn't bad and yes if drinking a electrolyte solution you MUST combine it with water otherwise you are just causing more harm and not hydrating yourself. The 1 ounce to 10 ounce soultion is very weak so it should do no harm, but if you feel this is the cause then stop using the Pedialyte. Stress can cause many problems with these frogs and even people. They can easily have a stroke from it.
Now no more baths. Let her be and keep her calm. Feed her and once or twice a week soak her in her own dish of plain water. Sounds like she may have had a stroke and has developed a neurological disorder. This may heal itself in time, but some do not ever recover. As long as she will eat she may make it.
