My baby girl who is turning 10 months old, fully breastfed, has been having diarrhea for more than 2 weeks now. No vomiting no fever, just very clingy and fussy at times. She goes 4 times a day with loose, watery, sour smelling, dark algae green color (sometimes brown), stool. I ve been giving her probiotics for two days now but no difference. Should I be worried?
