2 months of infants cough can be seen in physiological phenomena, pathological conditions (such as respiratory infections), whether or not it can be self-healing with the causes of cough, need to be analyzed on a case-by-case basis. 1. Physiological phenomenon: (1) Cough is a protective mechanism of the body, which helps to expel respiratory secretions. For example, infants who wake up in the morning may cough, usually with mild symptoms and no obvious progressive aggravation, which is a normal physiological phenomenon, and there is no question of whether the cough can be cured by itself, so it can be closely observed. (2) If the surrounding environment is dry or improper feeding, cough can also occur, usually can not be self-healing, avoid such factors cough can be relieved. 2. Pathological conditions: respiratory infections such as acute bronchitis and bronchopneumonia can cause coughing symptoms, some of which may be accompanied by wheezing and fever, which usually do not resolve spontaneously, and require prompt medical attention and appropriate interventions according to the degree of severity of the disease, including the use of cough suppressants and expectorants (e.g., cough syrups for pediatric patients) to relieve the cough, and the use of antibacterial drugs (e.g., cefaclor) to fight infection when bacterial infections are suspected. These medications should be used under the supervision of a physician. When a 2-month-old baby develops a recurrent cough or even a gradually worsening cough, it is recommended that he or she be seen by a physician to be evaluated by a specialist and given appropriate intervention.
