Girls, my daughter is 5.5 months old. She has had watery stools for the past two days. The first day I noticed it and thought it would pass, but the next day it was still the same. I gave her enterosgel and Regidron. The stool remained watery. Now before bed I gave her Stopediar. Tomorrow I want to have a stool analysis done. What's that? It doesn't help at all, has anyone experienced this? There's no fever or vomiting.
