Early Development Program

I recently talked with my cousin about child's early development program.

She is a mother of two young children... three and five year old.
She sends her kids to learn a pretty much everything, includs her three year old little girl.
Consistenly memorizing the words..
Watching dvd(s)...
Doing assignments until late at nights...

They learn... math, science, spanish, music, korean... plus extacurricular activities.

My cousin believes that doing those activities will lead them to go to the "good" colleges.
They are doing great for thier ages. She believes her kids have to learn when they are young. It because the kids' brains are like the "sponges" and absorbes everything that they have learned.

I don't know if I should agreed or not........
