Isn't this awful? You pretty much have to wait it out. If he/she will drink anything - most doctors suggest to get them to sip pedialyte (sp?). When kids are sick - our doctor suggests the BRAT diet (bananas, rice, applesauce, toast). Good luck -it's no fun. What feels the worse - is that you're the one they're looking for to help them - and there's nothing you can do. We've been there. Cuddle, cuddle, cuddle.
