There are many solutions for a four-month-old baby who has a cold, and the decision needs to be specific to the baby’s cold. If the child only has a stuffy nose, runny nose, and no cough, and the fever is in a relatively good mental state. At this time, it is enough to give the child more water, let the child rest more and pay attention to the changes in the child’s condition. If there is a slight cough, or a poor mental state, or a fever. In this case, you should treat your child with cold medication, such as pediatric anti-viral combination, pediatric black beetle and fever granules, or pediatric aminophenol pseudomal dispersible tablets. If it is accompanied by red throat or mild cough, you can give your child Pudilan Anti-inflammatory Oral Liquid for anti-inflammatory treatment or pediatric An’erning Granules for treatment, which are more effective. If the child’s cold is not relieved by the medication, but worsened, it is necessary to go to the hospital immediately.
