How does darling 4 months cough have a fever to do

Your baby's cough and fever at four months old are mostly caused by pneumonia or bronchitis. You need to take your child to the hospital for blood routine and C-reactive protein tests to confirm the cause. Follow the doctor's advice and use cephalosporins for anti-inflammatory treatment. When your child has a fever, try to feed him more water and supplement water. When his temperature is higher than 38.3 degrees, feed him antipyretics as soon as possible to cool him down.
