Young children are blessed with amazing linguistic abilities. I believe that learning in Chinese for two years actually improved all of her language skills - Mandarin and English. In fact, you'll find this interesting DaughterofEve, she is the only student in her class that actually read The Lion, The Witch, and The Wardrobe before seeing the movie.
P.S. Our nanny is originally from Beijing and speaks exclusively to both our daughters in Chinese.
Well, wish her Happy New Year for me! :-)
Brava! (that's not Chinese, of course!) : ) DOE
