Babies with phlegm will not cough can be fed water, back patting, nebulization and so on to help the baby discharge phlegm. 1. Feed water: If the baby has a lot of phlegm, you can feed the right amount of warm water. The water can dilute the phlegm, which is conducive to the discharge of phlegm. 2. Back patting: Because the baby’s cough reflex is weak and his ability to expel phlegm is poor, you can help him pat his back from bottom to top, which is also conducive to the baby’s phlegm expulsion. 3. Nebulization: you can follow the doctor’s instructions to use such as inhalation budesonide suspension, inhalation acetylcysteine solution and other phlegm expectorant drugs, as a nebulizer used to dilute the phlegm, to help the baby to expel phlegm. When the baby has a lot of phlegm, parents are advised to bring their children to the hospital in time, with the help of the doctor to clarify the cause, and actively cooperate with the doctor to deal with or treat.
