Home care

• Let your child get back to normal activity as soon as they feel up to it.

• This health problem can sometimes come back. Watch your child for signs. Look for belly (abdominal) pain that gets worse, or vomiting. Also look for crying spells without a cause and drawing the legs up toward the belly.

• Feed your child a normal diet.

Follow-up care

Follow up with your child’s health care provider, or as told.

When to contact your child’s health care provider

Contact your child's health care provider right away if your child has:

• Fever (see below).

• Belly pain that comes and goes.

• Constant belly pain that doesn't get better or seems to be getting worse.

• Vomiting.

• Extreme sluggishness, tiredness, or fatigue.

• Dark, mucus-like, bloody stools.

• Pale skin color.

Fever and children

Use a digital thermometer to check your child’s temperature. Don’t use a mercury thermometer. There are different kinds and uses of digital thermometers. They include:

• Rectal. For children younger than 3 years, a rectal temperature is the most accurate.

• Forehead (temporal). This works for children age 3 months and older. If a child under 3 months old has signs of illness, this can be used for a first pass. The provider may want to confirm with a rectal temperature.

• Ear (tympanic). Ear temperatures are accurate after 6 months of age, but not before.

• Armpit (axillary). This is the least reliable but may be used for a first pass to check a child of any age with signs of illness. The provider may want to confirm with a rectal temperature.

• Mouth (oral). Don’t use a thermometer in your child’s mouth until they are at least 4 years old.

Use the rectal thermometer with care. Follow the product maker’s directions for correct use. Insert it gently. Label it and make sure it’s not used in the mouth. It may pass on germs from the stool. If you don’t feel okay using a rectal thermometer, ask the health care provider what type to use instead. When you talk with any provider about your child’s fever, tell them which type of thermometer you used.

Below are guidelines to know if your young child has a fever. Your child’s provider may give you different numbers for your child. Follow your provider’s specific instructions.
