<s>[INST] I have a 4 year old that has a fever of around 100 hands and legs are cold has shivers will drink but not eat. Have vomited a few times but only mucus the little food he will eat has stayed down. Any suggestions? Have been giving him meds for cold and fever. [/INST] Hi,It seems that he might be having stomach virus giving this problem.This will remain for 2-3 days.Give him plenty of liquids and water and keep him well hydrated.Give him light and liquid diet for 2-3 days.Give Tylenol syrup for fever as needed.Ok and take care. </s>
