Most bronchitis in 6-month-olds is a complication of viral infections such as the common cold and influenza. Once your child is diagnosed with bronchiolitis, it is best to hospitalize him/her first. During the treatment, it is necessary to pay attention to the comfort of the environment, indoor air circulation, at a temperature of 18-20 ℃, humidity 60% is appropriate. And be sure to ban smoking and odors to reduce the factors that trigger the child’s cough. At the same time, it is also necessary to let the child rest on the side, the head slightly elevated, to prevent respiratory secretions flow into the airways. It is recommended to give the child more warm water to dilute phlegm, breastfeeding, the mother’s diet should be light. Because the child is relatively small, if taking the phlegm and cough medication does not work you can use nebulization to help treatment, but be careful to avoid overdose as well as too long a period of time. Generally speaking, it will take another 5-7 days of fluids for the symptoms to subside.
