There is no such thing as a “magic trick” to treat a two-year-old baby’s cough with phlegm; it usually requires symptomatic treatment. When a two-year-old baby has a cough with phlegm, it is important to check the severity of the cough and phlegm. In mild cases, the cough can be treated without medication by drinking more water, encouraging coughing and patting the back to relieve the symptoms. If the symptoms are more severe, you can add medication for treatment. I. Non-pharmaceutical treatment 1. Drink more water: If the performance of coughing and coughing phlegm is not too serious, you can drink more water appropriately, and you can also add honey appropriately. A small amount of addition helps to relieve coughing and coughing phlegm; 2. Encourage coughing: When a two-year-old baby has a cough with phlegm, the use of cough suppressants is not recommended, and phlegm must be coughed out from the body through the action of coughing, so it is not recommended to stop coughing, and it is recommended to encourage coughing Therefore, it is not recommended to stop coughing, and it is recommended to encourage coughing to achieve the purpose of phlegm excretion through coughing; 3. Patting the back: when the baby is coughing, the baby can be put in a side-lying position while the parents hold the five fingers slightly flexed into a hollow fist shape to pat the back, usually using the order of alternating sides from bottom to top and from outside to inside, which can promote the loosening of phlegm in the lungs and bronchi and flow to the large airways, which is conducive to phlegm excretion and alleviate the symptoms. Second, medication if the cough and coughing phlegm are more serious, the symptoms can be relieved by the following ways: 1, nebulized inhalation: babies can use nebulized drugs to dilute the phlegm, such as budesonide and amiloride, which help dilute the phlegm by nebulization and reduce the inflammatory response, which is conducive to the recovery of cough and coughing phlegm; 2, oral medication: if it is not very convenient to do nebulized inhalation, you can also consider taking expectorant cough medicines, such as Chuanbei Loquat Paste, Lung Ning Granules, Orange Red Phlegm Cough Liquid, etc. In addition, attention should be paid to finding the original cause of the cough. Most coughs and sputum are caused by acute respiratory infections, and if they are caused by bacterial infections, antibiotics such as amoxicillin and other anti-infective treatments are needed to help relieve symptoms and shorten the course of the disease. If it is a viral infection, antiviral or anti-infective treatment is usually not required, but simply waiting for the viral infection to resolve on its own, with subsequent relief of the cough and sputum symptoms.
