most of the diarrhea in children can be managed with ORS only,with paracetamol if febrile.antibiotics needed with blood in stools/high fever only...in that case too,more important thing is to maintain hydration with ORS...whether there is antibiotic or not,it will take 5-7 days for motion to be in control-but you need not worry;just replace the lost fluid with ORS.if oral intake is poor from vomiting,needs intavenous fluids,other wise,just wait. i hope you will find this information useful.wishing you a faster recovery.thank you.
