When to Call Your Doctor

Call 911 Now (your child may need an ambulance) If
  • Not moving or very weak
Call Your Doctor Now (night or day) If
  • Your child looks or acts very sick
  • Signs of dehydration, such as:
    • Has not urinated in over 8 hours
    • Crying produces no tears
    • Very dry mouth (rather than moist)
    • Sunken soft spot
    • Excessively sleepy child
  • Too weak to suck or drink
  • Refuses to drink anything for over 12 hours (8 hours if under 12 months old)
  • Refuses to drink and new onset of drooling
  • Could have swallowed a foreign body
  • Wheezing or stridor with breathing
  • Difficulty breathing not better after you clean out the nose
Call Your Doctor Within 24 Hours (between 9 am and 4 pm) If
  • You think your child needs to be seen
  • Unexplained difficulty drinking and also has fever
  • Poor drinking present over 3 days
Call Your Doctor During Weekday Office Hours If
  • You have other questions or concerns
Parent Care at Home If
  • Drinking adequate amounts of fluid AND no signs of dehydration and you don't think your child needs to be seen

  1. 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, since your child doesn't have diarrhea or vomiting.
  2. 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.
  3. 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 a liquid antacid as a mouthwash 4 times per day after meals.  
    • Give acetaminophen (e.g., Tylenol) or ibuprofen for pain relief.
  4. For a Blocked Nose: Suction it out using warm water or saline nosedrops in infants and toddlers. Make saline nosedrops by adding ½ teaspoon of table salt to 1 cup (8 oz.) of warm water.
  5. For Shortness of Breath: For mild bronchiolitis or difficult breathing, offer small frequent (every ½ hour) feedings so the infant can rest briefly between them.
  6. Call Your Doctor If:
    • Difficulty swallowing becomes worse
    • Signs of dehydration
    • Poor drinking present over 3 days
    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
