My kid who is 1.5 yrs had acute diarrhoea a week back.He had fever and runny stool for 2 days and now the stool is mushy and still not hardened like normal.Today is 7 th day after the onset of flu.Dr said not to give any antibiotics.How long will it take for the stool to become normal..Should I again take to doctor and ask for antibiotics? He is taking food and water as normal now though.
