<s>[INST] My 3 year old did not eat anything today but I noticed 4 nights ago he gagged on his tea & since then he hasn t really wanted to eat anything, his poo has been runny also. Child health say that toddlers won t starve themselves & say they are fussy eaters but I don t think this is the problem as 2 weeks ago he was eating normally? [/INST] Your child is suffering from viral infection of abdomen. The symptoms are poor appetite , nausea, loose stool and often fever. There is no treatment for it, only give him plenty of fluids and give sometime, It will recover. No antibiotics are required. Just give him probiotics like Enterogermina 1such twice daily for 3days.He will be ok in 5 days. </s>
