Coughing is protective for the body. Coughing removes mucus or irritants from the trachea, bronchi and throat and prevents them from entering the lungs. Most coughs in children are caused by colds and usually clear up naturally within 1 to 2 weeks. However, if the child has a cough with a significant fever for more than 3 days; if the cough persists for more than 2 to 4 weeks (when the cough is already prolonged or chronic); if the child is unable to eat because of the cough or vomits frequently because of the cough; if the child has wheezing episodes or a barking cough with hoarseness; if the child has nasal agitation, difficulty breathing, or purple lips or skin; if the child has a history of significant choking and When choking on food or other objects, etc., it is still important to seek medical attention to avoid delay. These accompanying symptoms may indicate pneumonia, asthma, laryngitis, respiratory failure, bronchial aspiration, etc. and should not be taken lightly. Do I need a strong cough to stop coughing? Because of the protective effects of cough, the side effects of cough medicine, and because cough suppression itself does not help the disease to improve, the abuse of cough medicine is prohibited up to the age of 2 years, and strong cough suppression of unknown etiology should be avoided up to the age of 5 years. You can give your child some honey water or pear water with rock sugar to help with the cough. Once the cause is identified, treatment should be tailored to the disease. For example, a child with bacterial pneumonia may need antibiotics; a child with acute laryngitis or asthma needs nebulization; a child with a lot of phlegm needs to have the phlegm removed to stop the cough; a child with a bronchial foreign body needs to have the foreign body removed to make the cough better. How to take care of a coughing child at home? 1. Adjust your child’s sleeping position: children with acute rhinitis and laryngitis often have difficulty lying down, so it may be more comfortable to hold her/him or put up a pillow. 2. These will increase the child’s loss of water from the airway, so it is important to drink a small amount of water several times to replenish the body’s moisture. 4. Air humidity: dry air can aggravate a cough, especially in the cold days of northern winter, when parents see their children coughing and turn on the heating, but the children may cough more frequently; in fact, the indoor temperature should not be too high, and putting a humidifier will help. Especially for children with acute laryngitis, breathing some cold outdoor air will make the situation better.
