If you are concerned that your baby might have a fever, the best way to check for one is to use a rectal thermometer. This can be a simple procedure that is not too uncomfortable for your little one.

1. If your baby is hot to the touch and feels warm when you kiss his or her forehead, you might want to check to see if there is a fever. This can most accurately be done with a rectal thermometer. It is important that you purchase a thermometer that has a rounded bulb and is specifically termed a rectal thermometer.
2. Step 2

   To ease the pain and discomfort associated with a rectal thermometer, you should use some petroleum jelly on the end to lubricate the thermometer. This will help the thermometer slide more easily and gently into the baby’s rectum. Petroleum jelly is not harmful to the baby so use it to provide more comfort.

3. Step 3

   It is important that you do not insert the thermometer too far into the baby. The goal is to insert just the end of the thermometer into the baby’s rectum about one inch. After insertion, hold it there for about two minutes to ensure an accurate reading. You should always keep a tight hold on the thermometer, so the baby doesn’t squirm and push it further inside. If the temperature reading is below 101 degrees, the the baby does not have a fever that is of any concern. If it is above 101 degrees, contact your local physician for further instructions.
