AmandasmomI agree with LynnT about triple dosing for diarrhrea caused by the antibiotic. Yeast infections in the diaper area are pretty common, especially with little girls on antibiotics. Get in touch with your pediatrician for a antifungal cream. Amanda got yeast infections all the time, even when not on antibiotics. If your daughter is old enough to eat yogurt with live cultures that should help with the diarrhea. Id check with the pediatrician.
Good Luck and I hope she feels better soon!
