Diarrhoea is commonly associated with infant teething. A variety of potential causes range from changes in diet to bacteria from an object the baby put in his mouth to increased drool from the teeth. The main concern with diarrhoea is the potential for dehydration. Stopping the diarrhoea requires taking measures against potential bacterial infection and dehydration.
Give the baby frequent bottles of formula, milk or some juice, but keep juices to a minimum. Dehydration is the most likely problem to occur when a baby is teething and has diarrhoea. Make sure the baby has enough to drink. If dehydration occurs, take the baby to the doctor.
Change foods the baby eats. Some foods can potentially cause diarrhoea in a baby. During teething, babies are often given foods to help deal with the pain in their teeth, but the foods must also prevent diarrhoea. According to Baby Slumber, rice cereal, carrots, bananas and potatoes help minimise diarrhoea.
Clean and sanitise any objects the baby might put in her mouth. When a baby is teething, everything goes in her mouth as she tries to relieve the pain. Give the baby clean teething rings to chew on, and keep anything that is potentially dirty, such as pet toys, out of the baby's reach. Bacteria are another potential cause of diarrhoea while teething, so minimising bacterial sources helps.
Take the baby to the doctor. If diarrhoea persists despite diet changes, sanitation and constant fluids, take the baby to the doctor for a checkup. If the baby has a virus or bacterial infection causing the diarrhoea, the doctor can prescribe appropriate medication.
Take the baby to the doctor immediately if the baby is showing signs of bacterial or viral infections, such as diarrhoea with a fever or vomiting.
