<s>[INST] My 8 mo old has been vomiting and or diarrhea after nearly every breastfeed; 24 hours ago stopped vomit but still diarrhea, also very runny nose and some coughing. Not sure how to assess dehydration- he is not peeing much but mouth still wet and nose is runny, he is sad but looks ok. Do I need to do anything right now or just wait it out? [/INST] you can classify dehydration as no dehydration some dehydration and severe dehydration sunken eyes, no tear, dry mouth tachycardia(increased heart rate)  prolonged skin tugot(when you pinch skin it take times to become normal) the best thing you can do is start on ors with probiotic and prebiotic sachet and zinc oral drops for diarrhoea with ondensetron drops and sinarest drops for cold every loose stool give 100ml of ors continue with breast feeding allow of plenty of oral fluid if baby is lethargic decreased urine output decreased activity take him to hospital if baby have continues fever spikes better to start with antibiotic </s>
