<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 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>
