Kids language education question

My kid is starting kindergarten this year, and we enrolled him in a Chinese language immersion school.  As sort of a prep to it, we sent him to a week long immersion summer camp.  Quite frankly, there was a very brief introduction to the language.  He learned only a handful of words, mostly how to say a couple colors and hello and goodbye.  And I'm sure that since my wife and I know absolutely no Chinese and can't help to keep it going, he will forget it all within another week.  But he had a lot of fun, learned a little about the Chinese culture, and is now really excited about getting to go to school and speaking the language.  So if you're going to do it, go in with the attitude that it's nothing more than a fun camp that might possibly give your kid the desire to begin learning a second language. 

FWIW, we chose Chinese over Spanish and French because by the time he graduates highschool they will most likely own us.  So being fluent in the language seemed like it had the most potential to open doors.

Interestingly, my oldest daughter learned French in school.  She worked at it and became reasonably fluent.  She now lives ahd works in Brazil and has had to learn Portuguese.  Her work is conducted in mainly in Portuguese.  She translates between her US or London customers to her Brazilian team.  Brazil is an up and coming country with vast natural resources, particularly oil and gas. 

It is good to learn a foreign language and with the Latin languages there is some carry over from one to another.  Spanish is a great choice.  My daughter's company wants her to move to a Spanish speaking country and become proficient in that as well so she can work with all their South American offices.  Having language skills opens a lot of doors.

Youngest daughter was in a Spanish immersion program from kindergarten through junior high school.  Half of the school classes were taught in Spanish every day by a native Spanish-speaking teacher.  She now works in research studying language acquisition.
