If your baby has hard ear wax, you can use a cotton swab or small tweezers to remove it if it is relatively small. However, usually babies will not cooperate because they are relatively small, so you have to be extra careful when taking them out. If there is movement in the process of taking it out, it may cause damage. If the earwax is large, it is recommended that you go to the hospital and have your doctor remove it with a professional instrument or a suction device to suck it out. If the earwax in the external ear canal is close to the deep part of the ear canal, especially if it is close to the eardrum, the doctor will soften it with medication, which takes 2-3 days, and then the doctor will flush it with water or use an ear suction device to suck it out.
