How does a one-year-old baby have sputum to help drain sputum?

When a one-year-old baby has sputum, parents should feed the child more boiled water to dilute the sputum. You can also use the empty palm from top to bottom, from inside to outside, gently pat the child's back to assist expectoration. When the symptoms are serious, it is recommended to take the child to the hospital for aerosol inhalation treatment.
