I am sure you know who Amy Chua is, author of Battle Hymn of the Tiger Mother from a few years back. She hired Chinese nannies when her daughters were young.  My understanding is that Amy agreed to raise their children Jewish (her husband’s religion) but they had to learn Chinese.  Sophia, the elder daughter, just graduated from Harvard and should be attending law school at Yale, where her parents teach.  You can listen to Sophia’s Chinese in this video.  Though Sophia had a script and likely practiced her part beforehand, Amy did a good job, considering their circumstance.  It took me sometime to find this video back then.
