<s>[INST] My 16 month old boy started vomiting and diarrhea on Saturday. Vomiting stopped on Sunday, but diarrhea has not. It is mucusy and foul smelling. He does not have a fever now, but did at the beginning. Today, he is getting red spots around his belly button and they are spreading up to his chest. He had his 15 month wellness checkup on Monday and dr wasn t concerned. I am starting to get concerned now that the spots started. Ideas? Not eating and drinking very well at times through this. [/INST] Hi...Thank you for consulting in Health Care magic.It seems your kid is having viral diarrhoea. Once it starts it will take 5-7 days to completely get better. Unless the kid's 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 diarrhoea.I suggest you use zinc supplements (Z&D drops 1ml once daily for 14 days) & ORS (Each small packet mixed in 200ml of potable water and keep giving sip by sip) as hydration is very important and crucial part of treatment. If there is vomiting you can use Syrup Ondansetron (as prescribed by your paediatrician).Hi...Thank you for consulting in Health Care magic.It seems your kid is having viral diarrhoea.

I suggest you to upload photographs of the same on this website, so that I can guide you scientifically.Hope my answer was helpful for you.  I am happy to help any time.
