If your child was born in the year 2000 or beyond, he/she should be learning to speak Mandarin.
With the current world dominance of the Chinese economy and China's strategic outlook of hundreds of years, your child will be at a severe disadvantage, if he/she does not learn Mandarin - a language spoken by over 850 million Chinese.
(Thus making it the most-spoken language on earth).
President Obama's 9-year-old daughter, Sasha, got to practice the Chinese she learned in school, with Chinese president, Hu Jintao, when he visited the USA some days ago.
We need to take a page out of his book and ensure that our children are equipped with this very important second language, so as to ensure that they have a fighting chance of working and doing business in this new century, that will be dominated by China and other leading Asian economies. :)
