It is still common for a seven-month-old baby to have a cough that causes spitting up. First of all, when coughing, the pressure in the chest cavity is increased, which in turn will compress the abdominal cavity, causing an increase in abdominal pressure, which will compress the child’s gastrointestinal tract, so that spitting up will easily occur. When coughing, it is often a respiratory infection, most likely an infection in the throat. The throat is a common channel between the respiratory and digestive systems, and when inflammation occurs, it will not only cause respiratory symptoms, such as coughing, but also digestive symptoms, such as vomiting, so the child will cough and spit up milk. It is recommended to give oral aminoglutethimide solution, pulmonary cough combination, and compound fresh bamboo liquid to the baby for treatment. If there is an elevation of white blood cells, antibiotics should be given at the same time, for example, cefixime pellets for children.
