For a 1-month-old baby with cough, you should observe the accompanying symptoms, such as whether the baby has a fever, whether the baby eats milk well, whether the baby vomits, whether the baby has diarrhea and other basic conditions. If your baby only coughs occasionally, and the rest of the baby is generally fine, and sleeps peacefully, and does not affect the milk intake, you can temporarily give your baby Aizhuang, let him/her rest more, and observe again. If your baby has a fever, is not eating milk well, is not sleeping well, and is not in good spirits, you need to go to the hospital immediately to find a professional doctor to treat your baby. Generally speaking, the hospital will take a chest X-ray and check the blood count to see if the baby is infected with bacteria and if the blood count is high. If there is an elevated blood count and signs of infection, the doctor will usually hospitalize the baby, usually with antibiotics. If the film shows signs of pneumonia, the baby will be treated with antibiotics for at least 7 days.
