Tayro speaks Spanish and English. His wife, Noriko, speaks Japanese and English. They currently live in an English-speaking country and have a new baby, Kai. They would like him to speak all three languages and have asked for your advice

What would you tell them?
a. Because he is learning three different languages at once, Kai will probably be significantly behind his monolingual peers on language milestones.
b. They should speak all three languages to him, but he is not able to hear the differences in languages until age 12, so there is no rush.
c. As an infant, Kai can distinguish between sounds in all languages until 9 months old. He should be exposed to all three languages during this time.
d. The best thing would be to hire a trilingual nanny who speaks English, Spanish, and Japanese because neither of his parents speaks all three languages.

Answer: C
