<s>[INST] Dear Doctor, our baby girl is two and a half years old and started vomitting two days ago accompnied by fever.we gave o r s and crocin .now fever has gone and vomitting stopped but loose motion has started.(twice this morning) [/INST] Hi... Thank you for consulting in Chat Doctor. It seems your kid is having viral diarrhea. Once it starts it will take 5-7 days to completely get better. Unless the kids having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. There is no need to use antibiotics unless there is blood in the motion. Antibiotics might worsen if unnecessarily used causing antibiotic associated diarrhea. I suggest you use zinc supplements (Z&D Chat Doctor.  </s>
