If you think your baby is running a fever, use a rectal thermometer to get the most accurate results. Place your baby on his or her stomach, or on his or her back with legs pulled up. Coat the base of the thermometer with petroleum jelly, and insert it slowly into the anus – only about half an inch, so that the metal part is inside. Hold the thermometer still, and, when it beeps, remove it and read the results. Any rectal temperature over 100.4 degrees Fahrenheit (38 degrees Celsius) is considered a fever. If your baby is less than three months old, you need to call your doctor immediately or seek treatment at an urgent care center or emergency room. Young babies have very weak immune systems; their bodies cannot handle the minor infections that would not pose a risk to an older child or adult. If your baby is between three months old and twelve months old, you should call your doctor if the rectal temperature rises above 102.2 degrees Fahrenheit (39 degrees Celsius). If your baby’s fever persists for longer than a day or two, even if it never rises about 102.2 degrees Fahrenheit (39 degrees Celsius), you should see your pediatrician as soon as possible. Certain symptoms warrant immediate medical treatment – either from your pediatrician or, if you cannot reach him or her right away, from an emergency room. Some of these symptoms can be hard to identify in young babies, so use your best judgment and err on the side of caution.
