Call your pediatrician for advice. Withhold milk products and give your child clear fluids like water or apple juice. Give infants commercial electrolyte solutions. Infants and young children can quickly become dehydrated. Causes of diarrhea may include change of diet, bacterial or viral gastro-intestinal infections and some medications.
Diarrhea often is associated with nausea and vomiting.
If your child is having severe abdominal pain, do not delay calling your physician. The soft spot on top of an infant's head may be depressed. An early sign is a decrease in voiding. Pinworms are intestinal parasites that cause no serious problems but do result in intense anal itching. Sometimes tiny, white, thread-like worms can be seen around the anus at night or first thing in the morning.
