If the baby’s boogers are pushed in, it is recommended that the family stop immediately, otherwise the boogers will be deeper and more difficult to remove, and once pushed into the nasopharynx and fall into the trachea, they can easily become a foreign body in the trachea, causing the child to choke and cough or even choke, which can easily induce lung infections and other diseases, and the following treatment can be taken clinically for this situation: First, the family can use a special nasal aspirator for babies to suck out the boogers. If the boogers are relatively large and hard, it may be more difficult to do so. Secondly, if the first method is not possible, the baby can go to the hospital and the doctor can use a few drops of medical saline to soften the boogers and suck them out under the guidance of the nasal endoscope, which is safer. If the baby has a small amount of boogers, they can flow out slowly on their own.
