Bilingual Avenue With Marianna Du Bosq

We are a Spanish couple living in a bilingual area where Spanish and Valencian are spoken equally. Our son is 3.5 years old. I have always talked to him in English since he was born. His father has talked Spanish to him. And he has been exposed to Valencian since he was 2 years old, first at nursery school and now at school. He understands everything I tell him in English but only on rare occasions does he answer me back in English. He says some words in English, but he’s hardly never able to build simple sentences spontaneously. I have used different strategies when he answers me back in Spanish. I usually repeat the sentence in English and then he says “yes”, but he doesn’t repeat them in English. In the last days I pretended not to understand what he was saying in Spanish to see if I could “force” him to speak English to me. But then he went to talk to his father and asked him the question in Spanish. Sometimes I think he is not getting enough exposure to English. He is at school from 9 to 5 and some days
