There are roughly two reasons for a 1-year-old baby’s runny nose: 1, the baby will have a runny nose in case of cold and acute upper respiratory infection, and at the same time there may be sneezing, fever, light cough, etc. 2, because the baby has an allergic reaction may also only runny nose, accompanied by sneezing symptoms and so on. If it is caused by cold factors, oral cold medication can be given, which can be combined with anti-viral oral solution and other drugs at the same time, and can be cured in about 1 week. If it is caused by allergic factors, we need to find out the allergens to avoid allergic reactions, and give oral anti-allergic drugs, which can be combined with drugs for nasal runny nose, such as nasal abdomen and orifice granules, which can obviously cure the child’s symptoms.
