usually antibiotics doesn t required bcz Diarrhoea doesn t normally require treatment other than to ensure the baby is getting enough fluids to avoid dehydration. Diarrhoea will normally resolve untreated, gradually within several days. If a baby is becoming dehydrated, a doctor may advise giving him or her extra water or oral rehydration fluids - available from your local pharmacy or chemist or by prescription from your GP - in between feeds or after the baby has a watery stool. Avoid giving your baby fruit juices (or older children fizzy drinks), which can make diarrhoea worse. Breast-feeding and bottle-feeding should continue as normal. In severe cases, a baby may need to be hospitalised and given rehydration fluids through a tube known as a nasogastric tube – it goes through the baby s nose and into the stomach – or intravenously through a vein. Your doctor may want a poo sample to rule out other infections or causes if your baby has bloody stools, is particularly unwell, if food poisoning is a possibility or you have recently travelled abroad.
