A child of deaf adult, often known by the acronym coda, is a person who was raised by one or more deaf parent or legal guardian. Ninety percent of children born to deaf adults can hear normally, resulting in a significant and widespread community of codas around the world, although whether the child is hearing, D/deaf, or HH (hard of hearing) has no effect on the definition. The acronym koda (kid of deaf adult) is sometimes used to refer to codas under the age of 18. The term was coined by Millie Brother who also founded the organization CODA, which serves as a resource and a center of community for children of deaf adults as an oral and a sign language, and bicultural, identifying with both deaf and hearing cultures. Codas often navigate the border between the deaf and hearing worlds, serving as liaisons between their deaf parents and the hearing world in which they reside. The coda identity Many codas do not identify with the "hearing world" or the "deaf world". Rather, they simply identify as codas: a bridge between the two "worlds" as they often find themselves in the middle of two. While codas might find some similarities between themselves and their hearing peers, they might also find that their upbringing within the Deaf community and culture sets them apart. Codas with cochlear implantation are often even more mixed between these worlds. They communicate with their families through signing but with the hearing world through talking. Potential challenges facing hearing codas The challenges facing the hearing children of deaf adults parallel those of many second-generation immigrant children. Just as many first-generation immigrant parents frequently struggle to communicate in the majority (spoken) language, and come to rely on the greater fluency of their bilingual children, so deaf parents may come to rely on hearing children who are effectively fluent bilinguals. This dynamic can lead codas to act as interpreters for their parents, which can be especially problematic when a child coda is asked to interpret messages that are cognitively or emotionally inappropriate for their age. For example, a school-aged child may be called on to explain a diagnosis of a serious medical condition to their deaf parent. In addition, codas are often exposed to prejudice against their family. The isolation can deprive the child of normal social skills. Many people may assume that the entire family is deaf because
