The proposal of bilingual education for the deaf have been largely discussed. In this theoretical principle, the deaf must acquire the sign language, as first language, by natural way and a second language, the predominant language of listener society (in the oral and/or writing form) based on the first language learning. In this text, are discussed some important aspects about LIBRAS (Brazilian Sign Language) and its cognition by the deaf child, regarding the development of the language, cognition and social interaction. The importance of the deaf child insertion in the deaf community for the formation of identification and cultural process will also be discussed, with the aim to take professionals involved in deaf people education to reflect about the LIBRAS importance to the deaf.
