I just received some junkmail from a company selling a kit (complete with videos, booklets and cassettes) that is supposed to promote foreign language development in young children. The company's website is early-advantage.com, and courses are available for several foreign languages. I'm not so interested in whether the company can prove all the indirect claims regarding higher SAT scores and IQs; my goals are a little less lofty. I'd just like to introduce my 20-month-old daughter to Spanish but am not sure that this course is worth the $170 investment. I'd like to know whether anybody has used this system and what they think about it if so. Any better products that you'd recommend? Thanks!
