A baby’s forehead not hot on both sides is mostly a symptom caused by fever in children. Because children have more blood vessels circulating on both sides of the head, which causes both sides of the head to be hotter. The blood vessels in the forehead area are less and fine, so when you touch it with your hands, you will feel that your forehead is not hot but both sides are hotter, which is a normal fever reaction. Parents should monitor the child’s body temperature in time, the axillary temperature exceeds 38.5 ℃, to take antipyretic drugs. For example, acetaminophen, ibuprofen, etc., these two drugs have a good antipyretic effect on children with fever. Next is to treat the cause, because fever in children is only a superficial phenomenon, the underlying cause is mostly due to infection causing fever.
