Do you realize...
That the brain forms at 250,000 neurons per minute while you are in the womb, and continues to form until you are five years old (most of it completed by the time you are two)?
Most people fill the first couple of years with Teletubbies. This is actually the best time to introduce languages (other than your own) to the child. The brain is born with a blank slate and begins making neural connections from birth. By the age of five, many of the connections are made - and permanent - and by the age of twenty your brain slowly begins to disintegrate (your learning ability disintegrating along with it). A two year old's brain is literally making language connections every minute, and if you don't feed that brain with good food and information, it will lose the chance forever.
Think about it.
