It is normal for milk to come out of the nose of a newborn baby. Immediately after feeding, you should hold the baby upright and pat the baby’s back to burp and avoid milk reflux. At the same time, when you put the baby down, you should slightly cushion the upper half of his body, which can also reduce the reflux of milk. This is because the common passage between the nasal cavity and the oral cavity is the pharynx, the newborn’s stomach is in a horizontal position, and the tension of the pylorus is higher, the tension of the cardia is lower, when the baby is not immediately erected after feeding the milk, it is easy to cause milk reflux. Therefore, when feeding, the mother should keep the feeding position appropriate, should try to feed sideways, and at the same time slightly elevate the baby’s head, to maintain a smooth airway during the feeding process. After the baby has finished drinking milk, the baby should be put upright immediately and the baby’s back should be patted gently. If the baby’s mouth milk overflow, you should immediately clean up the surrounding milk, pat the back, to avoid choking and coughing caused by lactic stasis pneumonia.
