Try to allow half an hour a day to play, read and write in this language. Cases of hearing children of deaf parents give us valuable information. These children who are native speakers of sign language have very little exposure to spoken language. A study has shown that television alone does not teach these children to speak. On the other hand, an average of 8 hours per week of language stimulation allows these children to learn to speak normally. We can conclude that it is the quality of the interactions, the richness of the vocabulary and the supports that promote the emergence and acquisition of the language in children and not the duration of exposure.
