Diarrhea is the passing of loose, watery stools. Vomiting is throwing up food and fluids.

Your child may lose large amounts of fluids during diarrhea or vomiting. This is called dehydration. You need to make sure your child drinks enough liquids to prevent dehydration.

What you should do for vomiting

  • Give your child plenty of liquids such as:
    • water
    • an oral rehydration solution such as Pedialyte®
    • ginger ale
    • Popsicles®
  • Start by giving your child small amounts: 2 to 3 teaspoons every 10 to 15 minutes until she stops throwing up.
  • After that, slowly increase the amount of liquids by 1 to 2 ounces every 30 to 60 minutes as long as your child doesn't throw up.
  • Don't give your child:
    • soft drinks (pop)
    • fruit juices
    • fruit punches
    • sports drinks

What you should do for diarrhea

  • Your child should drink at least twice as much liquids as usual.
  • Give your child an oral rehydration solution such as Pedialyte®.
  • Don't give your child Pedialyte® for more than 24 hours without calling her health care provider.
  • Give your child food when she feels like eating again as long as she is not vomiting.
    • Keep breastfeeding or formula feeding your infant or toddler. (Talk with your health care provider about using formula made to treat diarrhea before you use it.)
    • Good food choices for diarrhea are noodles, crackers, oatmeal, rice cereals, bread or toast, potatoes,bananas, applesauce, and turkey or chicken.
    • Avoid foods that are spicy, sugary or that have fructose (high-fructose corn syrup).
    • Offer your child yogurt with active cultures (such as Dannon®, Yoplait® or Activia®.)
    • Give your child probiotics such as lactobacillus acidophilus. Two examples are Culturelle® and Lactinex®.
