Hi Sanne, What colour stools is yor daughter passing?Smelly?? No temp? Any signs of abdominal discomfort? ie not just when shes having diarrhoea? Does she cramp,bend over,pull her legs up @ any time? Points to her tummy crying? Have you introduced any new foods into her diet recently??(prior to this illness) It does sound rather viral but you could take a stool sample to your gp for her to have it analized to check for viral or bacterial infections ( you'll need 2 stool samples for these tests.) Regards, Dana RSCN
