How does a newborn become deaf?
Genetics is the cause of hearing loss in many babies. Genetic hearing loss can be present at birth or develop later in life. The genes that cause hearing loss can come from one or both parents. You both may hear fine but carry a gene that causes hearing loss in your baby.
