If a three-month-old baby has boogers, parents should not use external force to forcefully pick them out, which may cause damage to the nasal mucosa of the child. Vitamin AD drops can effectively soften the boogers, which can be discharged from the nasal cavity smoothly with the child’s breathing. Third, if the amount of nasal stool is large, you can also give local nebulized inhalation saline to wet the nasal stool, which can be discharged from the nasal cavity.
