Has anyone tried the glen doman baby Flashcards. Does it really work to teach baby math at a young age?

Currently struggle on whether should I introduce my baby Flash Card. Share this with u and tell me what do you think? http://blog.sina.com.cn/s/blog_476e6cfa0100ek0o.html Unfortunately it is in Chinese. Quick Summary here: - Temporary ability. This kind of ability will be reduced by the time ur kids' growing up (once right brain is fully mature). As baby's left brain will be grow slower than right brain. - Conflict. right and left brain manage different sectors. right mostly art and left mostly numbers, languages.
