At what temperature does a baby develop a fever?

Question

My son is 11 months old, the rectal thermometer shows a temperature of 38 degrees. He blows his nose a little

38 degrees is the beginning of a fever, but it is not at all alarming. From 38.5 or 39 degrees, you need to keep a close eye on the child's general condition. You should go see a doctor if your child has stopped eating or is very ugly.
