Definitely call the doctor. Also, follow the BRAT diet (bananas, rice, applesauce and toast). This diet is low in fiber and stops you up. Also make sure you are using desitin or some other cream for rash. My toddler had a number of bouts with diarrhea and always ended up screaming in pain from diaper rash. Make sure your little one is staying hydrated with pedialyte and water. No apple juice either. Good luck!
