Earwax buildup can be caused by a variety of factors, including overproduction of earwax, foreign objects in the ear, and ear infections.

The best way to clean an infant's ears is to use a warm washcloth. Cotton swabs can push earwax further into the ear canal, and bulb syringes can be too harsh for an infant's delicate ears.

Otitis media is the most common type of ear infection in infants. It is an infection of the middle ear, which is located behind the eardrum.

Hearing loss in infants can be treated with hearing aids, cochlear implants, speech therapy, or a combination of these treatments.
