Newborns have snot is a normal phenomenon, because the baby’s nasal cavity is relatively short, the nasal mucosa is delicate, rich in capillaries, a little change in the external environment, such as the temperature is low, too dry, dust, irritating odors and other stimuli, will cause the baby to sneeze, and thus also snot. The baby is lying down for a long time, and the swallowing action is not well developed, so the snot will stay in the nasal cavity for a long time, after a long time, the snot dries up to form a dry nasal crust, which is also the reason why parents find that there are dry boogers in the baby’s nasal cavity. If the dry boogers are close to the front of the nasal cavity, they can be cleaned up directly with a cotton ball, and if the dry boogers are deeper in the location, they can be softened by dropping a few drops of saline, and then sucked out with a nasal aspirator. If the dry boogers are deeper, you can soften them with a few drops of saline and suck them out with a nasal aspirator.
