If a 7-month-old baby’s temperature is measured in the armpit, the normal temperature should be between 36 degrees and 37 degrees. 38 degrees is definitely considered a case of fever, but it is a case of hypothermia, so don’t be too nervous. First of all, you need to observe what discomfort your child has, find out the cause of the fever, and treat it for the cause. If your child has a fever caused by a cold, if the temperature exceeds 38.5 degrees, you should give your child medicine to reduce the fever. You can give your child pediatric ibuprofen suspension, the specific dose needs to be used according to the child’s weight and in accordance with the instructions.
