A report I found today talks about a school in Seattle called sponge which aims to teach babies and children four languages - Spanish, Mandarin, French and Japanese - through play, songs, stories, etc. They have teachers who are native speakers of the languages they teach and take children from as young 5 months and up to 5 years old.

This sounds like an interesting approach to language teaching and I’m sure that children will benefit from this multilingual environment. I wonder whether they’ll become fluent in all the languages though - they may not get sufficient exposure to each to acquire them fully. Perhaps that isn’t the point of the school.
