Phlegm in the throat of newborns is also a relatively common phenomenon and has many causes. First of all, we should pay attention to whether there is a softening of the laryngeal cartilage, which sounds like a whirring phlegm sound in the throat. Secondly, we should pay attention to the weak swallowing function of newborns, which may not swallow some milk completely after eating milk; there may also be fatty body condition of the child, which belongs to the body with spleen deficiency and phlegm, or it may be caused by respiratory tract infection. The cause of the disease is complex, so the first step is to figure out the cause and choose the appropriate treatment. If there is phlegm sound in the throat within half an hour after feeding, and it disappears later, it is considered that the swallowing of milk is incomplete, and can be treated without treatment. If it is a baby with spleen deficiency and phlegm or too much milk, you can reduce the amount of food appropriately or use some medicine to eliminate phlegm. It is also important to pay attention to the possibility of respiratory tract inflammation. Newborn babies with phlegm in the throat should be distinguished from the causes. First of all, pay attention to the breastfeeding mother who should also pay extra attention to the diet, try to eat light things and refuse all raw, cold and spicy foods, otherwise it will also make the child have symptoms of phlegm in the throat. Since newborns are relatively young, if the phlegm inside the throat is not discharged for a long time, it should also be treated with supplementary medication so as not to affect the breathing of the newborn. You can consult a doctor at a regular children’s hospital to help your baby improve the symptoms of phlegm in the throat with the help of a doctor to achieve the desired treatment effect.
