Seven-month-old baby coughs

The cause of your baby's cough is usually an infection caused by pathogens invading the throat, tonsils or bronchi, or even the lungs. If your baby has frequent persistent cough, it may also be caused by allergies. If your child shows symptoms of cough, you should pay enough attention. Because the child's respiratory system is not fully developed, if the sputum cannot be discharged smoothly when coughing, it may cause airway blockage, hypoxia, or even heart failure.
