How old is she? Isabella y Ferdinand has a Curso Intensivo aimed at bilingual children, up through age 10. Our 3yo is in it and most of the other children in her class are being raised mostly with Spanish in the home; our DD is more like 70/30 with English dominant right now. I think it's much more enrichment-focused and less intense than the Escuela Argentina. But we're also interested in this topic for future years, so thanks for posting!
