There is no danger of the baby’s boogers being sucked into the baby’s stomach, i.e. through the throat and esophagus into the stomach, which is generally not dangerous and does not lead to significant discomfort. 2. If the boogers are crusty and particularly hard, there may even be transient difficulty in breathing and other related manifestations, and some patients may have the possibility of holding their breath and holding purple, and the boogers themselves carry many viruses and bacteria, which may easily induce patients to develop bronchitis, pneumonia and other diseases. Clinically, babies with nasal discharge should be cleaned up regularly with a suction device or buy a special nasal aspirator for infants.
