When a baby has phlegm, it is best if you can give your child some medicine, especially for younger children, to prevent the child from transforming into a case of pneumonia. If a slightly older child does not take medicine, you can give the child a dietary treatment, for example, you can use garlic and rock sugar to boil water for the child to drink, you can usually use three cloves of garlic, a bowl of water, and then add half a spoon of brown sugar and boil it for 10 minutes. In severe cases, you can give your child 3 times a day. If drinking garlic and rock sugar water does not relieve the problem, it is better to give your child some medicine. If it is a case of yellow sputum, you can give your child pediatric cefixime granules for treatment. If the sputum is white and thin, you can give your child Pudilan Oral Liquid for Anti-inflammation. In addition, it is best to give the child the oral solution of pediatric aminoglutethimide to reduce phlegm.
