Home Care (Read "Call Your Doctor…" first):

Increase Fluid Intake

Give your child unlimited amounts of her favorite liquid (e.g. chocolate milk, fruit drinks, Kool-Aid, soft drinks, water). The type doesn't matter, as it does with diarrhea or vomiting.

Solid Foods

Don't worry about solid food intake. It's normal for the appetite to fall off during illness. Preventing dehydration is the only important issue.

For Sore Mouth

If the mouth is sore, give cold drinks. Avoid citrus juices. For infants, offer fluids in a cup, spoon or syringe rather than a bottle. (Reason: The nipple may increase pain).

Older child can use 1 teaspoon of an antacid solution as a mouth wash 4 times per day after meals. Give acetaminophen (e.g. Tylenol) or ibuprofen for pain relief.

For a Blocked Nose

Suction it out using lots of warm water or saline nosedrops. Make saline nosedrops by adding ½ teaspoon of table salt to 1 cup (8 oz) of warm water.

Call Your Doctor If:

  • Difficulty swallowing becomes worse
  • Signs of dehydration
  • Poor drinking present > 3 days
  • Your child becomes worse or develops any of the "Call Your Doctor…" symptoms
