When Ainoa was 3, she was already speaking Spanish with a Castillean accent. And if she uttered an English sentence, Shaku would say, simply and convincingly, “No entiendo.” And she stuck to it. As a result, Ainoa had to speak Spanish if she wanted to be understood. Now that she has been attending a bilingual school, this second grader is also reading and writing in Spanish. Argentine Fátima Sfiligoi is equally passionate about her language. “It would be very sad to be in Argentina and see that my children can’t talk to my mom.” So she speaks to her children, Chloe (7) and Kailen (5), exclusively in Spanish—whether they are at home or among non-Spanish speakers. Her children speak fluent Spanish, with correct pronunciation and a distinct rioplatense accent—an amazing feat considering that they go to a public school and spend the rest of the day with Charles, their stay-at-home dad who speaks to them only in English. Since Fati works full-time, she made it her mission to spend plenty of quality time with her kids in the evenings. “I get home at 6:30 and the day is not over for me.” When she arrives, the children switch to Spanish because they know that this is mami time. “We play, read books, listen to songs, we call my mom almost every day…” Like Shaku, Fati believes in formal education: every Saturday, from 10 am to 2 pm, her children go to the Argentine School in Queens.
