You might try more carbs than bananas & applesauce from the BRAT diet to help "bind up" the poop more. I've also found yogurt to be helpful to help normalize her system, though at 8 months old I would check with your doctor first. They even sell probiotic powder which would be stronger than yogurt, but again I would definitely check with the doc before doing that. For her poor little hiney, spreading a liberal coat of vitamin E oil right out of the capsule might help, especially at night when it can sit there for a good long time. Good luck. The diarrhea will pass - she won't have it for the rest of her life! Hang in there!
