Coughing and vomiting are very common in two-year-olds, even in adults with more severe coughs. Coughing often irritates the throat and causes vomiting to occur. Coughing also causes a rise in chest pressure, which in turn leads to a rise in abdominal pressure, which can compress the gastrointestinal tract and cause vomiting. First of all, the cause of the cough should be identified and treated. In most cases, a two-year-old baby’s cough is due to a respiratory infection, and the first step is to check the blood count to see if the infection is bacterial or viral. If there is an elevated white blood cell count, it is a bacterial infection and the child needs to be treated with oral antibiotics, such as pediatric cefixime pellets. If there is no elevated white blood cells, it is a viral infection and can be treated with Pudilan anti-inflammatory oral solution combined with cough and phlegm relieving medications such as Ambrotero oral solution.
