A fever can be a sign that the body is fighting an infection. Learn how to properly care for your baby, toddler or child with a fever.

Key points

  • Fever is usually a sign that the body is fighting an infection.
  • A temperature of 38°C (100.4°F) or higher means a fever.
  • See your doctor if your child has a temperature that lasts for more than five days or if your child has a fever and is less than three months old.
  • Pay attention to how your child looks and acts. Keep a record of the number of days of fever.
  • To keep your child comfortable, dress your child lightly. Give your child lots of fluids to drink, and give acetaminophen or ibuprofen if it seems to make your child feel better.
