Hi. Ok I conferred with Redwuff, and it is agreed that you should give your baby girl the following.
Mix 1.5 Tablespoons of Sugar, along with a 1/2 teaspoon of salt too two cups of water. Make sure it is all mixed real good. I suggest you use hot water to mix it, it will desolve much better. Then cool it to just warm not hot and she if she will take that. This should only be given for one day ONLY.
Check her as it goes in case she dose dehydrate but I don't thin she will. Do you know how to do the pinch test for dehydration?
