Hi One year old child with greenish stools indicates a viral diarrhea. And actually doesn t need specific medication. If there is no vomiting then this can be treated with oral rehydration therapy. Let her take 100 ml of ORS per loose motion. If she is passing urine well then it indicates she is well hydrated. Consider giving her probiotics and zinc supplements. Look for vomiting, blood in stool, fishy smell of stool, not passing adequate urine, high grade fever, excessive crying. If so please consult Pediatrician. For her fever give paracetamol according to her weight. Hope this helps you.
